We have found out that, when this triggers, it only happens when moving the mouse, I'll be posting a video soon.

DXVK does not interact with mouse input in any way, I strongly doubt it's even remotely possible that this is our bug.

Also haven't seen anything like this on my machine even in extended play sessions. As for Unreal Engine titles, I ran Hellblade and Days Gone for ~an hour not too long ago to test some unrelated changes.

I understand that they don't interact with mouse input, but when I run a game that natively uses Vulkan (ie. Quake 2 Remastered, Saints Row) they're not affected by this problem.

Switching to any of your releases paired with a vkd3d release completely fixes this mouse problem. I'm not any more expert than you, but the only thing dxvk and vkd3d have in common is dxgi.

I don't know if I'm being helpful but I can post a video on YouTube or logs.

Well what I'm saying is that this functionally doesn't make any sense and I can't reproduce it.

First step would probably be to provide detailed info about your build environment, including compiler version, MinGW version if applicable, and the exact command lines you're using to build the whole thing.

Another question would be what kind of environment you're running on as well, any sort of input issue points more towards wine/compositor issues than us.

I'm using fully updated Arch Linux, MinGW 13.1.0-1.

I tried with X11, X11 + gamescope, Wayland and Wayland + gamescope. Same problem happens after roughly 25 to 40 minutes of gameplay.

There's an intermittent heavy stutter that runs at its own pace, but only when playing with keyboard and mouse apparently, and it gets worse if you move your mouse once the "timebomb" triggers.

I'm using your package-release.sh script to build dxvk, using vkd3d's package-release.sh script to build vkd3d as well. Nothing goes wrong while compiling. Switching to "old" versions of vkd3d + dxvk completely gets rid of the issue.

Running a game that natively uses Vulkan or OpenGL never triggers this problem (under the same proton prefix and under the same circumstances of course).

I'm going to upload a video of the problem on YouTube (recorded by a friend of mine) in order to showcase the problem.

Video uploaded, manually switch to 1080p if it starts at 360p. This is a footage after roughly 30 minutes of playtime. The lag "timebomb" shows up at 0:44 timestamp:

https://youtu.be/PNa_DGexFAs

Does this also happen with the builds that ship with Proton Bleeding Edge or downloaded from GitHub CI or only with self compiled?

Also are you able to bisect which commit it started with?

I'm using fully updated Arch Linux, MinGW 13.1.0-1.

This is precisely what the release builds are from. MinGW stuff hasn't been updated in a year or so, so the past couple of stable releases were compiled using exactly this in release mode.

Switching to "old" versions of vkd3d + dxvk completely gets rid of the issue.

Does "old versions" include self-compiled builds of stable releases?

I'm not running anything special here, just plain old KDE Wayland with (generally) no Steam overlay and (generally) no Gamescope, and RADV on a 6900XT. If this is an issue that supposedly affects any (UE4) game on any setup then what exactly is it that makes my system the special snowflake that this doesn't happen on?

Yes, to also answer @Blisto91 the "old versions" included my own self-compiled. I have self-compiled versions of both dxvk and vkd3d saved, but I don't know where to start, honestly, maybe we can guess something:

For the sake of having a complete background, I'm actually going to test this whole thing without using ecores on intel and by using only one ccx on amd. It's probably unrelated and nonsensical but it doesn't harm me to test, my boyfriend is also testing with me. We've been trying to troubleshoot this for days to no avail.

could you send a log with DXVK_LOG_LEVEL=debug

also could u try windowed mode

could you send a log with DXVK_LOG_LEVEL=debug

Yes, I'll attempt both things after testing the ecores/ccx thingy.

Edit: I'm sorry because these tests take a very long time, it's 25 to 40 minutes per-test. Yet, reproducibility should be easy (not timewise of course) as long as you're playing with a mouse and a keyboard on newly compiled dxvk + vkd3d.

Is it actually git cloned and compiled or just picked from releases? If nobody can reproduce this here, it could actually be related to a change that affects ecores (to-be-confirmed since my boyfriend is still testing, he's playing since 31 minutes without the problem triggering as of now).

Does not seem to be the problem. Will try no-occlusion straight away @doitsujin

Timebomb triggered at 33 minutes with this fork. Some walls and corners were invisible. My boyfriend will test this again with debug logging, I'm going to sleep soon. Make a list of more things that I should try and I'll do it right after waking up (I don't have work so I'm free the whole day).

Well, that rules out the only DXGI change since 2.4.1, so....

Could it be a shared change between DXVK and VKD3D? Because we don't experience that problem with neither Proton GE and Experimental, yet we used to not have that problem at all and I always compiled the latest git releases for both of us.

I strictly believe that, at some point in time, something changed, and it affected both dxvk and vkd3d, and specifically "mouse handling" (probably not the right term) somehow.

It's weird that anything that runs on native API (Vulkan / OpenGL) does not suffer from this issue on any Proton prefix, yet the moment we try using git compiled dxvk + vkd3d this starts triggering.

It's interesting that games that run, for example, on Insomniac Engine and its forks, don't even suffer from this issue, while other games (notably Unreal Engine) have this timebomb as long as they use DXVK or VKD3D and as long as you play them with a mouse and keyboard.

My boyfriend will provide debug logging until the problem starts happening, and if you can 100% conclude that this is certainly not a DXVK + VKD3D issue, I'll have to look somewhere else. Most worrying scenario would be this problem affecting the majority of people but they have no idea. We really need more people testing this.

Been playing Hogwarts Legacy for around 110 mins now but haven't been able to reproduce.
Proton Experimental Bleeding Edge (the beta branch), Ryzen 7950x, RTX 4080 (driver is 565.57.01), KDE X11, Steam overlay turned on and even obs open in the background.

That's not exactly the steps, I meant manually compiling dxvk and vkd3d straight away and putting them in a compatibility tool.

I asked above if the issue shows with the builds included in Proton Bleeding Edge or from the CI.

Edit: Could you share the ones you have compiled?

I asked above if the issue shows with the builds included in Proton Bleeding Edge or from the CI.

This will take a long time to test, I was mainly testing git compiled dxvk and vkd3d. Bleeding Edge breaks too much stuff, I'd rather live with the lag timebomb.

I would like to try the ones you have compiled yourself to test with. Just package them up and attach here

Played Hogwarts Legacy for 90 minutes more, this time with the Bleeding Edge DLLs replaced with vkd3d-proton, dxvk and dxvk-nvapi from your archive. Still nothing sadly

since you can build your own dxvk and know that the issue has been happening for 2 months, could you bisect it?

My boyfriend actually tried experimental bleeding edge overnight (without my DLLs) and the timebomb triggers there as well. Are you sure you were actually playing with a keyboard and a mouse? The problem only seems to happen when using m+k. Regular Proton Experimental is completely fine and unaffected by the way. And again: native Vulkan/OpenGL games running under any of these compatibility tools do not expose the problem, so it's definitely a dxvk+vkd3d thing.

since you can build your own dxvk and know that the issue has been happening for 2 months, could you bisect it?

See my message above where I list my older compiled dxvk+vkd3d combos, I don't know where to start. If you have an idea, maybe a date, I can start from there and test.

You say affected games mostly use Unreal Engine. Did you reproduce it with non-UE games? When you say, you don't have this issue with OpenGL/Vulkan, again those probably don't use UE?

Moving the mouse in Wine/Windows has the side-effect of changing the timer resolution of the scheduler, to react quicker. I observed this behavior when using the default c++ stdlib Sleep() function instead of specific Windows targeted Sleep(), maybe something to think about.

Are you sure you were actually playing with a keyboard and a mouse?

Yes. I rarely play with anything else.

Let's try to get a bisect going even if we won't find the commit in one day. Just try to test with the builds i send when there is time.

That is true, but how is it that it acts like a literal timebomb? AFAIK the problem should appear immediately.

Did you check your RAM and VRAM usage? When RAM/VRAM gets full over time, lags are usually the consequence.

They look fine, but this still doesn't exclude that there could be a leak somewhere (or memory management issues overtime), so you might have a point as well.

Yes, it happened. I attached logs. When the timebomb ticked, he left the game open for further 40 seconds (still playing normally of course) before closing it.

We just tested regular Proton Experimental again without changing anything and the timebomb just happened there as well, it just took 1 hour instead of the usual 25-40 minutes. I'll be attaching logs here. Knowing that regular Proton Experimental shows this problem as well, should I still try that dxvk version? As before, the timebomb triggers and then the game lags only when moving mouse, there are literal fps drops as well, basically as shown in the last YT video I linked.

Which path should I take from now? The problem is affecting 3 different system by the way and we're crushing our heads on the wall trying to understand what's wrong. We can run Vulkan games for 6 hours straight on the same compatibility tools (GE, LFX2, Experimental, etc.) and this timebomb NEVER triggers

Here are Proton Experimental logs if you can make use of them:
game_dxgi.log
game_d3d11.log

I'm so clueless at this point. Do I try the next build or do I take a different path?

Edit note just to reiterate: some games are not affected, like Horizon Zero Dawn Remastered, Ratchet: Rift Apart, Saints Row The Third Remastered and some more games are NOT affected by this, somehow. It's mainly Unreal Engine games that seem to be problematic and have this weird lag timebomb after X minutes.

I was eating, sorry for the late response.

My boyfriend was now testing the game without gamescope and using regular Proton Experimental (not Bleeding Edge) to rule out a Proton Experimental + Gamescope combo glitch (probably useless, but he's 31 minutes in already so the timebomb should trigger in a very bit), then I'll proceed and let him place the next dxvk build and as always I'll provide results and logs ASAP.

For reference, we're always using the same game in order to obtain coherent results.

Definitely, it's a Mouse + Keyboard input problem that only happens on DXVK + VKD3D

Once the timebomb triggers (25 to 40 minutes for Bleeding Edge and latest git dxvk+vkd3d on ANY proton version; 1 hour for unmodified Proton Experimental -> not bleeding edge <-), every keyboard input or mouse input causes the game to stutter regardless, you can clearly see it up on the mangohud overlay in the following video as well (ignore my boyfriend's voice if you can hear it):

Edit: My boyfriend is going to record the whole session with also mangohud's frametimes graph, and if the problem happens again I'll just post a video again with a lagless portion included. My boyfriend is also going to make a video with his phone, explain and show in detail what's happening. I will obviously include logs as always, additionally to the two videos.

@Blisto91 Same issue.

No idea what to try next.

After extensive testing and troubleshooting, I've decided to take a step back from Linux gaming for the time being. While I'll continue using Linux for my professional work, I plan to revisit gaming only after a considerable period, perhaps in a few weeks or months, hoping these issues will be resolved by then.

This very specific problem has become quite frustrating. I've found out that this now seems to happen even with regular Proton 9. I've tested this across three different hardware configurations, including a complete system reinstall, and unfortunately, the same issue persists. What's particularly concerning is that this problem always happens across various setups, including a full AMD system, and remains present regardless of whether I'm using X11, Wayland, or Gamescope in both of them.

While I totally respect that others might not be experiencing these issues, my experience tells me that this is not possible. At this point, rather than continuing to waste time, I'll be stepping away until there's a proper solution from whoever caused this, whether that's from Arch Linux, DXVK/VKD3D, or other involved devs. It's particularly BAD to encounter identical issues even after a fresh installation across multiple systems with different configurations, it's just not right.

I appreciate your efforts, but for now, I need to take a break from this thing and wait until this is all resolved.

Consider me unsubbed from this issue.

PS I personally and genuinely don't actually believe anyone who says that this problem can't be reproduced. Nothing personal.

If this was an easy to reproduce problem, you'd find more post about it online in various forums. I've never seen any such reports though and also never experienced this issue myself.

If this was an easy to reproduce problem, you'd find more post about it online in various forums. I've never seen any such reports though and also never experienced this issue myself.

I have reinstalled Arch Linux from scratch and this happens out of the box. Full AMD system. It just takes 25-40-50 minutes of mouse and keyboard input to trigger it. No chance that it can't be reproduced. I'll be out for the time being until developers find a solution, maybe 2 or 4 weeks, and then check back. Either Arch Linux devs did a whoopsie or dxvk+vkd3d did a whoopsie, I'm tired of endlessly troubleshooting this problem that I can't get rid of. I just tested now after a clean install and KovaaK started stuttering after 42 minutes.

If it also happens with older Proton versions then i am going to guess that it is this old issue https://github.com/doitsujin/dxvk/issues/2371
It is something we have heard reports of from time to time (Source 1 games being an example) but it isn't something we have ever been able to reproduce on our setups, not for a lack of trying, so it is hard to debug.
The best guess is that there is some overlay involved that starts to act up after a while with dxvk E.g Steam overlay or similar. But it is hard to say without some proper debugging which would require a dev or tester reproducing it.

It happens even without any Vulkan layer attached and, after triggering, only lags when sending mouse/keyboard input. This is all I can say. I have just wasted time on fully reinstalling vanilla Arch Linux on a full AMD machine just to see the exact same issue happening again. Please check all the videos above.

I'll try the LD_PRELOAD method, but KovaaK is a VKD3D game by the way. I already mentioned that this problem happens in both DXVK and VKD3D, but NOT if the game uses Vulkan or OpenGL as API.

This whole issue popped out of nowhere and even a clean reinstall doesn't solve it.

If YOU cant debug it, maybe give advice to those already having the issue on how to debug it???

but NOT if the game uses Vulkan or OpenGL as API.

Does this include Windows games using those APIs like Doom 2016 or Eternal? Because otherwise it would be conceivable that this is a Wine issue.

Vulkan games and OpenGL games running on any version of Proton don't have this problem. I and my boyfriend are experiencing this issue only in DXVK and VKD3D at the same time, everything else is completely fine under the same compatibility layers.

Note that i am not a dev but "just" a tester.

There was actually a "stutter after 40min" issues that sounds similar caused by the steam overlay a long time ago: https://github.com/ValveSoftware/steam-for-linux/issues/7505

LD_PRELOAD= %command% would work around it by completely disabling the steam overlay. Not sure why this ancient issue would resurface now though, and why almost no one else seems affected.

I have had this issue in the past where the frame pacing completly tanks after about the same time when using gamescope or mangohud for no reason

yes, better use dxvk overlay for these sort of tests, as you may as well run into a mangohud bug.

This happens even without any overlay. I'm currently testing with LD_PRELOAD="".
It's funny how this gets a "can't reproduce" tag when all it takes is a clean Arch Linux install.

maybe this bug needs high fps to trigger?

I'm on Arch and can't reproduce it at all either, I think everybody is already trying their best and nobody is even dismissing your issue.

Nope, also happens capped at 60 fps.

I maintained a professional tone until I clean reinstalled Arch Linux on a full AMD system just to see the same issue pop again. It's not really "my" issue when a clean distro installation doesn't get rid of the problem.

Maybe just tell me which distro both DXVK and VKD3D gurus suggest to use and I will install it.

I would really like to be able to try and reproduce the problem, trust me. But if we include the issue i linked above then i have tried several times through the years on probably 3-4 different setups by now, so i just really don't know what more to try.
Afaik all on the team use Arch (correct me if i am wrong)

I'll be able to tell you whether the LD_PRELOAD="" method works in 20 minutes, either way.

btw I also use arch (and can't reproduce), and I guess if that LD_PRELOAD thing doesn't work you can maybe try profiling proton and to see what's going on. (I haven't done this before, so you will probably have to look through some documentation and figure it out)

also are you using radv or amdvlk

Believe it or not, using LD_PRELOAD="" actually fixed the problem for me, even when adding mangohud and OBS game capture to the vulkan layers through VK_LOADER_LAYERS_ENABLE. I'm more than 1 hour in playing KovaaK using Proton Experimental Bleeding Edge and it's still buttery smooth.

Now my question is, what is Steam LD_PRELOADING into the game then? I digged a bit and found nothing.

My theory is that this "Record your game" thing on Steam somehow injects even without your overlay being active. Would that explain this whole "timebomb" situation and the timing? This is just a theory, but, as far as I'm concerned, this whole thing really just started happening around the time they implemented this new feature. Even though it's disabled on my side, I think that's what was causing the issue.

I could probably close the issue but, if anything, I'd like to know what Steam sets LD_PRELOAD to when launching my games. Do you know a reliable way to do that? Plus, my bf really just wants to first see this with his own eyes.

Now my question is, what is Steam LD_PRELOADING into the game then? I digged a bit and found nothing.

Probably some stuff for steam input, which would maybe explain why it's related to mouse input. You can check what steam sets LD_PRELOAD to when a game is running by looking at /proc/$PID_OF_THE_GAME/environ.

I could probably close the issue but

Yes, but please open a new issue about it referencing this one over at https://github.com/ValveSoftware/steam-for-linux/issues

This is the only entry showing in LD_PRELOAD when launching the game with default settings:

LD_PRELOAD=/tmp/pressure-vessel-libs-4PFQW2/${LIB}/gameoverlayrenderer.so

For reference, my Steam overlay is completely disabled.

What if you also manually disable steam input for the game? Maybe it also (intentionally or not?) loads the overlay stuff even if you disable it.

What if you also manually disable steam input for the game? Maybe it also (intentionally or not?) loads the overlay stuff even if you disable it.

Steam Input was already turned off because that game is an aim trainer, so I turned it off to not add useless layers on top of the game.

Yes, but please open a new issue about it referencing this one over at https://github.com/ValveSoftware/steam-for-linux/issues

I probably won't do it until tomorrow because I'm strained by all these days of troubleshooting and I just don't want to deal with more log grabbing and stuff. You can feel free to post an issue, or wait until I do it, it's the same to me.

I'm closing this specific issue because it's caused by Steam's LD_PRELOADs, thanks everybody who helped me find the culprit.

I will probably open an issue at https://github.com/ValveSoftware/steam-for-linux/issues tomorrow, but you can feel free to do so as well.

Actually, I just played overwatch 2 and did run into the same issue.

Haven't tried yet, but I'll probably play again today, have already setup LD_PRELOAD="" in the launch parameters.
I wonder how long this bug has been around, probably not for too long, since it's the first time I experienced it, but haven't been playing for a month or so previously.

Thanks for being persistent in trying to solve this issue, as it's definitely a rough one.

For me, it definitely started around the same time Valve implemented the "Record your game" thingy on Steam. And yeah I would say I'm quite persistent with things when it's not my fault, probably due to the way my work environment is (where colleagues accuse each others of having broken some code all the time), kinda reflects to other things I do.

Ran into the same issue about 3 days ago as well - Thanks for the LD_PRELOAD fix!

When you say your overlay is completely disabled, how do you mean? Have you taken any steps for that other than using the UI option in the Steam client to disable the overlay?

Completely disabled through Steam's UI.

Thank you for this thread @SheMelody. I thought I was going bonkers for the last few weeks looking for whatever it may have been. As I experienced this on a number of different games but not all games.

I appreciate the effort you went through on this.

Can confirm I have also been experiencing the same issue, but only since upgrading to Fedora 41. Couldn't find anything online and was thinking I was going crazy. Thanks for making the thread.

Having the same issue, stuttering occurred in Saitsfactory. Thought it was gamescope but turning gamescope off didn't resolve it. Happened in DX12 and Vulkan mode. Disabled steam overlay. Switched from Proton Experimental to GE-Proton-9-16

It initially seems to have been resolved by adding LD_PRELOAD="" to my launch commands.

Went stuttering in Satisfactory every 30-40m on mouse input that required a reboot of the game, to playing for almost an hour and half last session after adding the command without issue (wasn't able to test further).

Setting LD_PRELOAD="" seems to introduce input lag for me in Borderlands 2

Alan Wake 2 too had been showing some weird mouse lags recently (past month) on both Nobara 40 and Mint 22. It happens only if at least 15 minutes has passed. It simply will not happen sooner. I noticed this issue here, and tried to run the game on Lutris to see if lags go away and it was definitely fixed. I did not use LD_PRELOAD workaround for neither Steam nor Lutris.

I never compiled anything though... playing with default Proton 9/Experimental versions on both Steam and Lutris. I shall now try other games on Steam to see if they too have this mouse lag bug after 30 mins (tried Remnant 2 yesterday but I always rage quit it before 10 mins passed, despite trying hard not to. Now going to try Empire of the Ants and possibly Hellblade 2).

Ah! And god of war Ragnarok also has this problem!!
Empire of the Ants also has this problem.

I had this issue with Guild Wars 2. I want to also add what temporary fixed the time bomb was using the release version of DXVK. However this was my experience 2 weeks ago, currently experiencing mouse lag immediately in GW2. The fix for the 40 min lag time bomb was to use a release version of DXVK, however the immediate cursor lag I'm experiencing now is unrelated to DXVK. The current lag I am experiencing is worse with outside Value tree's of Proton. I've tested Experimental and GE Proton versions which have a 5-10 fps drop moving the cursor, however Proton or Wine compiled without value tree's shows a bigger fps drop moving the cursor. Again want to state this was only for Guild Wars 2, and not other games.

I had relief knowing this issue was made clear when noticed in CS2 massive lag spikes after playing 30 min , warframe too when doing nothing but not in Space Engineers (maybe because crashes before experiencing this lag).
Testing currently
LD_PRELOAD="/usr/lib/libgamemodeauto.so.0" VK_LOADER_LAYERS_ENABLE=VK_LAYER_MANGOHUD_overlay_x86_64 gamemoderun %COMMAND%

Did you mean Counter Strike 2 or Cities Skylines 2?

I seem to have a similar issue that after around 40-60 minutes of gameplay suddenly the game starts stuttering. Not sure if its this but Im gonna try LD_PRELOAD="" as well.

EDIT: Actually seems to have helped... no more stutters.

AMD Radeon 7900 XTX
AMD Ryzen 7950X3D
32GB DDR5 Ram

OS:
Archbased (CachyOS) Kernel 12.2
Plasma KDE 6.2
Wayland

Having same issue with Star Trek Online

Also happens in Path of Exile 2 with its Vulkan renderer, which would mean this is unrelated to dxvk?

I am seeing this also on Manjaro KDE running Fallout76 using GE-Proton9-20. The game runs perfectly smooth for about exactly 30 minutes or so then the jitter line in mangohud just goes crazy and the only fix is to restart the game.

Currently using this launch parameter:
gamemoderun mangohud %command%

I will try some of the above fixes and report back.

This was occurring to me in Path of Exile 2 with both DX12 and Vulkan.
With Steam overlay disabled, LD_PRELOAD="" did not work
With Steam overlay enabled, LD_PRELOAD="" worked
However, I did not test steam overlay enabled without LD_PRELOAD, so I cannot say whether that or enabling Steam overlay (or both) did the trick.

I am experiencing this in FarCry5. After almost exactly 27 minutes it occurs with a 4080 on 5900X at 5120x2160. Frametimes spike to 65ms in a sawtooth shape, from around 9ms.

LD_PRELOAD workaround works.

I had this issue with armored core 6 when I use gamescope to send it to my TV. But steam input doesn't seem to work as i can't use my controller with LD_PRELOAD in the launch command. Is there something I can do to force this?

Just started following this thread. I have a similar issue:

1. Start playing a DX11 Game
2. 30 Min Pass -> Game Stutters based off KBM movement

It doesn't matter if I use Steam Overlay, mangohud, or vkbasalt. I always end up getting stutters around the 30 min mark.

I have played a few DX12 and OGL games 30-Min-Stutter does not kick in. I will play a few other games and see if the same problem happens outside of DX11 games.

I have not tried the LD_PRELOAD= yet. I will read up on this some more and see if it works.

I bought a new GPU because a few peeps from the Bazzite Reddit suggested my low VRAM 4GB GPU was causing issues. I got a 12GB 7700XT and got the same 30-Minute-Stutters. Tried different BIOS settings and same issue has been popping up for a while now.

Hopefully this gets sorted soon.

The thing is steamoverlay.so is used by steam for everything these days,
you just can't disable it from running.

Just make sure that overlay option is turned off in options.

That option actually is a preload option and most likely preloading
steamoverlay.so by default, and resolves issues for certain folks in
certain situations.

Well, that's where things get funny:
Steam Overlay was already disabled in options because of https://github.com/ValveSoftware/steam-for-linux/issues/11479

Just adding to the list the two games I have encountered this exact same issue in. Same symptoms: game runs absolutely perfect then suddenly starts stuttering and the frame times go out of whack. The stutter is constant while moving the mouse, and less frequent while moving the player character with WASD; no stutter when no user input is being provided, i.e. NPC and background animations, player character idle anim etc. all fine. Using keyboard and mouse, no gamepad.

• Ship Graveyard Simulator 2 (Steam/Proton): stutter after 40-45 minutes depending on activity, in both in DX11 and DX12 modes. LD_PRELOAD="" workaround solved it.
• Shadow of the Tomb Raider (Steam/both native and Proton): stutter after 45-60 minutes. The issue was definitely present there in early September. The above workaround solved this as well, played 4 hours of it today with no stutters.

@DrymarchonShaun a GPU hang is a completely unrelated issue and also probably not a DXVK bug, more likely a driver bug. Report it here using the 'radeon vulkan' template https://gitlab.freedesktop.org/mesa/mesa/-/issues, also check out https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/docs/drivers/amd/hang-debugging.rst?ref_type=heads to gather more info.

None of these things seem to fix ffxvi s stuttering issues. But I have to
account for its poor optimizations of being a ported console game.

Star Trek Online however continues to experience stuttering issues after
running smoothly for 30-45 min even after applying these env variables.

Hmm, alright. If that's the case, then I must have multiple things
happening at the same time. I'm seeing a bunch of the symptoms described on
the issue on the steam-for-linux repo that came about from and links to
this issue, and the hangs seem to only happen when the steam overlay is
loaded.

This is insane. I have common launching script for all games, which deals with prime_run/gamemode/ kills launchers etc.
So I added

export LD_PRELOAD=""
unset LD_PRELOAD

Now ALL games are smooth like I updated PC for a million.
Valve should stop breaking things....

It's funny that this issue has existed for one year or more as far as I remember but people are still not understanding the nature of the issue.
I solved this infamous "28-min time bomb mouse moving stutter" by enabling steam overlay in CS2 (counter strike2). I ain't no programmer and don't know why it helped, but it's shocking to me that not only the bug has not been resolved till this day, but also no one seems to understand what's the source of the bug.

but also no one seems to understand what's the source of the bug.

Steam/ubuntu12_32/gameoverlayrenderer.so
Steam/ubuntu12_64/gameoverlayrenderer.so

Those are preloaded, 1 of them will print famous error in log. Because system is 32 or 64 and it tries both.
Any way, if someone never uses overlay (like me), then it is better to set it empty.

I just imagined ... what will happen if both can be loaded ? :) (for example system has multilib config). I guess they will fight each other => lag.

Yep, my bet is on 32 and 64 conflict each other when both are loaded:

Yep, my bet is on 32 and 64 conflict each other when both are loaded:

They should only actually load the correct version for the executable, not both. Easy to test, just set the LD_PRELOAD to one of them.

Yep, in addition, steam itself (and all it's children processes) are "infected" by 32 bit library on 64 bit multi-lib system.

Yep, my bet is on 32 and 64 conflict each other when both are loaded:

Why it only happens after a certain time, e.g. for cs2 it's somewhat 28-min.
Whose fault is this? Steam or linux distro?

It depends on the nature of the conflict. I also made chown root:root and cmod -r -w -x for that 32 bit library, so now Steam does not load any of them. Games just work and with good fps as it was 1-2 years ago.
If somebody needs browser overlay, it is better to setup OS keybindings (into DE config), it always overrides what game sets (at least for that DEs I used).

I've been able to reproduce this issue too on Fedora/KDE Plasma 6 (Wayland)/ProtonGE 9 22

So far only LD_PRELOAD="" seems to completely eliminate the problem, no severe stuttering after 40-45mins of gameplay.

I tried disabling GPU acceleration in web view without success.

I tried changing uid/guid owner and chmoding ~/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so, steam overlay isn't loaded as expected but the issue remains.
Maybe i need to do that on the whole ubuntu12_32 folder?

Not sure, I had 32 and 64 bits loaded. So I did LD_PRELOAD. Then I checked again both libraries using lsof and found that 32 bit is still loaded by Steam on startup. So I just banned it until lsof stopped to show it loaded. Try whatever is best for you, confirm by the lsof.
I did both. Because LD_PRELOAD stops for new game launched and chmod cleanses startup of the steam.

That's interesting, out of curiosity, i extended the scope of what was loaded and... this is quite confusing... i'll deep dive on it later to experiment.

this is quite confusing...

It is simple. Only 2 libraries are loaded there ;)
They're inherited. When Steam has loaded 32 bit library, anything it launches next (wine, proton, whatever script you have) - will have this library loaded + in addition proton loads 32 + 64 when it starts the game using LD_PRELOAD.

Indeed, i chown/chmoded the 32 and 64bits libraries and that fixed the issue, from there i tested keeping the correct 32bits overlay and that worked.

From the tests i've done so far (with a 32bits DX11 game)

• 32bits gameoverlayrenderer.so inactive & 64bits gameoverlayrenderer.so active => No Steam Overlay & Stuttering after 40mins
• 32bits gameoverlayrenderer.so inactive & 64bits gameoverlayrenderer.so inactive => No Steam Overlay & No issue
• 32bits gameoverlayrenderer.so active & 64bits gameoverlayrenderer.so inactive => Steam Overlay & No issue

I guess it's because a 64bits library is loaded with a 32bits game or the other way around (haven't tested it yet) causing this issue.
The question is why Steam is loading both at once... is it a normal behavior? What happens on a SteamDeck?
Could be a DXVK or PROTON issue as well not handling correctly these libraries with a 32bits or 64bits executable... (just a guess)

The question is why Steam is loading both at once... is it a normal behavior? What happens on a SteamDeck?

I can just speculate. As we see into LD_PRELOAD dump, it tries to load both. It has no sense if you know bitness. So this means, they didn't figure how to check current bitness and tried to load both. On plain Linux it would load 1 only though, because wrong bitness will fail unless you have multi-lib system.
That what I think.
But if you have stuttering with 1 loaded, then problem can be in library itself. For example, Windows has/had a "keyboard hook", that was a way to install the catch for any pressed key anywhere using DLL. And it had problem like here, if this hook was slow whole system was unresponsive. Probably they did the same for Linux to catch ctrl+tab. Any way, it is always bad idea to have any global hooks, I just removed it and don't bother. I admit though, voiding LD_PRELOAD may skip something useful in the future too.

On closer inspection, the culprit may be gamescope, i noticed that all 64bits gameoverlayrenderer.so are "not permitted" without it and with gamescope based on the 1st lsof i posted, one manages to be loaded by gamescope:

With gamescope, tries to load the 64bits one instead:

gamescope 75862                          slash  mem       REG               0,39              563097 /home/slash/.local/share/Steam/ubuntu12_64/gameoverlayrenderer.so (path dev=0,50)
...

Without gamescope, reaper (wine) loads the correct 32bits gameoverlayrenderer:

reaper    18456                          slash  mem       REG               0,39              563077 /home/slash/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so (path dev=0,50)

With gamescope, tries to load the 64bits one instead:

I don't have "gamescope" and still had a problem.
What you see there is inheritance, when binary starts new binary, that new one gets libraries of the parent loaded by the OS.
I have here complex chain of the bash scripts, which start bash and it has library, than this script restarts gamemode daemon for me and it gets library loaded too and so on.

Could be a wrong lead there for sure, i'll try to investigate while playing a bit more later, thanks for the help.

No, it's not gamescope.
As far as I understood, it's hanging within Steam's redirected input processing.

Just a heads up, the problem was confirmed to be related to the Steam for Linux, you should continue discussing it here: https://github.com/ValveSoftware/steam-for-linux/issues/11446

Although this problem doesn't seem to affect native APIs such as Vulkan and OpenGL, it's still not directly related to DXVK/VKD3D, although there's a correlation between gameoverlayrenderer.so and DXVK/VKD3D running under Proton.

Enabling Steam Overlay or else using a custom LD_PRELOAD statement such as LD_PRELOAD="" to preload nothing or LD_PRELOAD="something:something:something" to preload your things seems to completely workaround the problem. Steam Input will still continue to work.

The problem started happening since the game recording update for Steam.

Edit: Native Vulkan games (under Proton) seem to be affected as well, maybe not all of them.

Steam Input will still continue to work.

I have no idea what is it. So I would prefer to keep it completely removed in my setup. Thanks, though.

You only need Steam Input for PlayStation / Nintendo gamepads and such. Usually, the "default" setting works just fine.

Although this problem doesn't seem to affect native APIs such as Vulkan and OpenGL

This is only correct for OpenGL. Native Vulkan games (running via wine) are affected as well.

Yeah, I just saw some users having this problem on Vulkan, was never reported before and I never had them so I assumed it was fine.

I did run into this issue in Path of Exile 2 with its Vulkan renderer.
However the OpenGL game Slay the Spire was fine.

I don't get why they keep adding "features" which immediately break everything or make it worse. This one is not alone. They added GPU detection, which powers-on double gpu which raises heat and consumption just to keep steam opened, Had to block it by appguard.

Nah, this time-bomb stutter issue started long before. It has existed at least for more than a year. People reported it on CS:GO long long time ago, and the fix was similar: disable steam overlay or use 'LD_PRELOAD'.

for me LD_PRELOAD does nothing. and true that i had this time bomb before steam recording, however i only noticed it in CS2 and as i dont play CS2 for some few months, i havent tried to troubleshot this so cant confirm for sure is this related in any way.

why is this closed??

Because it isn't a dxvk bug.

Edit: A open issue about it can be found at the steam-for-linux repo https://github.com/ValveSoftware/steam-for-linux/issues/11446

My conscience has made me wake this issue up. I'm sorry. My conscience is doing this.

In my post above, I said I cannot play Remnant II for more than 10 minutes before Alt+F4ing it. The truth is, this game is actually very fun, it is me who sucks. I've been stuck at the last boss for more than a year now... this is why I keep rage quitting it fast, because I cannot handle the truth. That I suck at it. But this game is actually really fun... I was wrong to dishonor it.

I can finally sleep well.

We have found out that, when this triggers, it only happens when moving the mouse, I'll be posting a video soon.

Identical to what I see in OW2. Runs perfect for half an hour or so, then has issues.

While actually playing and moving myself, the game goes haywire, the symbol claims its lagging (but I see the same issue in Kovaaks which is offline) and it tries to claim its still 100 fps while it is chopping all over the place. But if it's playing a killcam (in the same game) it doesn't drop a frame. Moment i have control and move again it starts lagging.

Hopefully there will be no need for the empty LD_PRELOAD or forcing the user to use the steam overlay.

I wanted to report that I am also experiencing this issue now
It started this week with Borderlands 3 and now i get it today with Dishonored 2.
Im on Cachy OS, Kernel 6.14.5-3, Mesa 25.0.5, and tried the latest proton experimental and the latest Proton GE

This issue does not effect the steam deck

When adding LD_PRELOAD="" my controller does not work at all anymore
Someone experiencing the same thing?

Yes, because main goal is turn off steam's support for inputs, like controller by doing this ;)
You can try to configure controller outside steam somehow.
