It looks like the instructions referenced in the video (found at https://ludwig.im/en/projects/steam-pulseaudio-sound-latency-lagging-problem-noise#optimize-pulseaudio-settings-for-steam-games) corrected it for me. Specifically, editing the number of fragments and the size in my pusleaudio config to be
default-fragments = 5
default-fragment-size-msec = 2

seems to have eliminated most if not all of the crackle. I'm recommending making this config a default for my distribution (Solus). I believe this can be closed now, but I'll leave that for someone else, since I'm not sure about the procedures here around closing out issues.

I can't even get the launcher to work, how are you managing to get in game? For me the launcher just freezes almost instantly after logging in to it, and then has to be sigkilled.

Edit:
Found why the launcher kept breaking, Steam was generating a broken game install path in the registry. Apparently any print statement left in the user settings end up appended to the game path.

That was too quick. It now goes to the loading screen for a few minutes then shows a graphical screen with the title and in the log I get an endless sequence of:

If I search for this error, it looks like those should have been fixed in wine several years ago.

Hello. The game does not run on Proton 5.13-2. After the launcher, I get a black screen. I also tried to leave it there for an hour but there was no change.
I put in the attachment the log.

Hey Kisak,

Here is the gist:
https://gist.github.com/Zabrat01/7c927a23744be81fca1b33f90b308bdb

As for the Proton log, I assume you mean putting the PROTON_LOG=1 %command% in the "General" area of Properties? I did try that but cannot find the file. I am new to Zorin OS to be honest. Thank you.

I think I may have found it..

steam-9900.log

Interesting. Last year ARC had forced an "Account Linking" between Steam and ARC. Afterward, I would log into Steam but it would pull up a new character creation screen as if am a new player. I have over 1,200 hours on STO. I did ask them to fix it at first but they were not sure how to. If I selected back to the login area I could then log in. I was still on Windows at that time. So, a couple days ago I asked them to unlink my account between Steam and ARC. They did just last night and when I used Steam to launch, it asked me to Link again, I did but this time it went to my character screen directly. So it is fixed in this sense. I wonder if it had anything to do with that? So basically I can access it now via Steam/Proton using Experimental again. Thanks all.

@kisak-valve Thanks for the quick reply!

I have to correct myself. At this moment, the game is not running on Proton 7.0-1, and ProtonGE 6.21-1 (just for reference), but it is running with Proton-Experimental!

@Kepsz What does the failure look like for you?

For me (never played before), the launcher went through its patching process, and I am able to launch the game client. The servers are down for maintenance right at the moment, so I can't proceed further. But it appears to be working up to that point.

@aeikum I think they patched the launcher today, because it is now working fine with both Proton 7.0 and Proton-Experimental. Yesterady, there was an error message about the unsupported OS, and no launcher at all.

Btw, there are one thing that newer worked with proton so far, that's the "on-demand patching". We all have to deactivate that feature in the launcher. - other than this, the game worked fine.

Ah great. Just to confirm, it's working as well for you now in 7.0 as it was before in 6.3 and/or Experimental?

Yes. I played for an hour now with 7.0, it worked exactly as Experimental!
I have never played the game with 6.3, I've been using the Experiment for as long as it exists.

Great! Thanks for reporting and retesting. The game's launcher using an "Engage" button to start the game made me laugh :)

Recent reports on protondb and my own experience indicate that the game works fine on Proton 7.x but does not render properly on 8.x, I got a black screen and the game music.

steam-12456498923395088384.tar.gz

Using GE-proton 8-3 just tabbing a few times (sometimes the first time) and when tabbing back in its just straight black. I can with GE at least play without tabbing.

Thanks kisak. I dont remember why I added it but I assume at some point I had issues and protondb comments pointed to it. But removing WINED3D does seems to solve the issues for me.

debug.txt

Hello,

the game stopped working on my system. I tried proton experimental, 8.0, 7.0, but none of them worked. The game doesn't start at all, ass soon as I click on the steam button "play" it immediately terminate.

Works fine on my PC (EndeavourOS KDE) with proton Exp.

You can try:
-check the game files for errors in steam, it will resets the launcher files too
-launch steam from terminal and check the output for errors / missing things

Well, something is not right with this game or proton. I have 2 PC's, same OS, same software, exactly same hw except for memory, but that should not matter at all.

PC1:
STO works fine with Proton Experimental

PC2:
STO launcher instantly crashed with Proton Exp and Proton 8. At this time, I did a steam reset, but it solved nothing. Then I tried to reinstall the game. The launcher did only worked with Proton 7, but the game was unable to load. One day later, I was able to launch and play the game with Proton 8, but not with Proton Exp. Meanwhile, STO works fine on PC1 with proton Exp.

PC Specs:
EndeavourOS KDE, always updated, kernel 6.4.1
Ryzen 5800X
Amd RX6700XT with mesa 23.1.3

On PC2, I tried to get logs from running Steam from terminal, but did not seen any relevant output.

Hello @Kepsz, on "PC2", please add PROTON_LOG=1 %command% to the game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.

Hi!

Btw, there was a launcher update today, and since then, it is now broken with Proton 8.0 too. The launcher loads, but the window content is completely black. The log for that:
steam-9900_proton8.log

"701.452:014c:0150:err:module:import_dll Loading library kernelbase.dll (which is needed by L"C:\windows\system32\kernel32.dll") failed (error c000012f)."

This reads like the Proton Experimental install on your system is damaged or incomplete.

Oh yeas, it was. Now integrity check did fixed it. Thx for the note!

So in PC2, right now both Proton 7, 8, and 8 exp is able to run the STO launcher. But the launcher does only shows a black screen. It works otherwise, the buttons are there, just nothing is visible. There are many vkd3d errors in the log file.
steam-9900.zip

Other games like Cyberpunk works fine with proton exp. I may be able to check STO in PC1 today. Maybe.

*update: the situation is the same on PC1 too. vkd3d errors.

The launcher atm is still showing a black picture. Some times the game is able to start after clicking the not visible start button, but in most cases it freez.

Replying to https://github.com/ValveSoftware/Proton/issues/1198#issuecomment-1633682261

To fix that you can use the --disable-gpu launch option. Later the game will still work on the GPU.

In my case the game works well but it does not close. It always hang at the closure then I am able to close it with the "force quit" option proposed by Ubuntu.

With today's proton-exp update, there are some syntax error within ?skia? vkd3d shader compliation (most detailed from line 5749):

C:\fakepath:33:35: E5000: syntax error, unexpected '(', expecting ';' or ','
steam-9900.log

@fbenedett thx, --disable-gpu works with the launcher.

The Iconian gateway symbol-matching game, as seen in ”Sphere of Influence” part “The Other Side”, does not display any symbols. This makes it effectively impossible to complete, with the only practical option being to skip the mission.

Tested with radv and lavapipe; Mesa 23.1.5, navi23.

@fbenedett thx, --disable-gpu works with the launcher.

Since STO got an updated launcher, it is now working fine on both of my machines. The game works fine too.

Re. the missing graphics in “Sphere of Influence” – looks like that's a known issue and is affecting Windows too. Other missions are affected in similar ways – I saw another which has a sometimes-electrified floor; it's just not possible to see when…

Anyway, I'm seeing random startup failure (main game) – works fine with Steam overlay switched off, falls over a lot while displaying “Cryptic” and the initial progress meter otherwise (but does start up sometimes).

[Edit] Discussion with @kisak-valve on IRC pointed me at ValveSoftware/steam-for-linux#9586. Tested with Big Picture a few times, no startup failures.

Steam build timestamp 1694301770.

When Star Trek Online is launched via Steam with either the latest proton experimental (as of 3/22/2024) and also Proton 9 Beta - the launcher is completely black and unusable. This appears to be a problem with Valve's official Proton software (Proton Experimental and Proton 9 Beta). Using --disable-gpu in the launch options does not fix it.

Steam Version: 1709846872

Side note: The launcher works completely normally (not a black screen) in GE-Proton 9-1 but the same black screen problem happens in GE-Proton 9-2.

I tested it with proton experimental, but STO launcher works fine on my 2 PC's. Both have AMD 6700XT, with mesa 23.2.4.

@alasky17 Thank you so much for getting back to me! I can confirm that the proposed workaround does work and fixes the issue with 9.x (currently 9.4 at the time I wrote this) for me! Sincere thanks! I really appreciate it.

Side note - I suspect Champions Online and Neverwinter may be similarly affected since the those games (I believe) use the same launcher (reskinned) and the game engines are basically the same.
