You can click slightly below the top left corner to start the game, where I drew the green box.

I have no audio but this is probably a separate issue.

note: this still doesnt work with faudio, but installing xact to the prefix and using the xaudio2_7 override works

The latest FAudio deals with one issue where the submix ordering was wrong...

https://github.com/FNA-XNA/FAudio/commit/8e0883d9b3e3d0dedde83a234eb93e551b9b4a4f

... but I've narrowed down the hideous noise to one of the submix effects. If you comment out this block, the sound is okay:

https://github.com/FNA-XNA/FAudio/blob/master/src/FAudio_internal.c#L1005

I have no idea what the problem effect in question is, but if it's an effect in the engine and not one of ours, we could be in trouble...

Well, this isn't good. Out of the 7 unique effects I was able to identify, none of them are known effects. They're not ours and the CLSIDs are not familiar to me at all.

It seems like we're doing everything right; all the flags are accounted for, LockForProcess succeeds, and the effect in question is in-place so there shouldn't be any uninitialized memory (the bug sounds the same every time, FWIW). The only thing I can possibly think of is parameter update accuracy, but without access to the effects I have no idea if that's relevant.

Point being, it's somewhere in either SetEffectChain (FAudio.c) or ProcessEffectChain (FAudio_internal.c) but that's all I know.

Out of random curiosity I decided to add support for the SILENT flag in the XAPO spec and... uh, it sounds okay now?

https://github.com/FNA-XNA/FAudio/commit/5f8e1f0bc71867dca5310143bc3ceecc778023fd
EDIT: Did I really think f32 PCM would never be < 0...

I don't feel like this should make sense, but I did notice that they don't set their effect parameters until 1 update after it starts processing, so maybe it's a very specific case where silence initializes some stuff and by the time real sound starts pushing out, it coincidentally happens to be ready for real samples. I'm completely fabricating that idea though, so if you try upstream FAudio be on the lookout for more screeching.

3.16-6 includes the latest FAudio, should resolve sound issues for this title.

Strange brigade runs great now using the vulkan exe. getting an avg of 90fps on vega 56 ultra @1440p. Audio works perfectly now thanks!

Hello everyone.
I have similar issue with running game Strange Brigade on Ubuntu system.
When game loads then goes back to desktop.

I have fresh install of Ubuntu:
Description: Ubuntu 18.04.1 Bionic LTS
I have everything up to date.
Using Proton 3.16-6 Beta.

This is my PC hardware [Lenovo Y720]:

It's a lot of code:

Anyone?

The game mostly playable if not enabled tessellation. With enabled tessellation even impossible select character because of graphics artifacts. I don't know which render are used by default (DX12 or Vulkan) so I can't say which are culprit here vkd3d or RADV driver.

Hello @NTMan, please add PROTON_LOG=1 %command% to the game's launch options and drag and drop the generated $HOME/steam-$APPID.log into the comment box. Also, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.

System Information
Strange Brigade benchmark with enabled tessellation

@NTMan, but Mr. kisak-valve does not give solution to problem only collecting logs.. :(

The tessellation issue with RADV is fixed with:
https://cgit.freedesktop.org/mesa/mesa/commit/?id=b155f74d7bfc9daec7794074c4f644025fbddf8b

The fix should be in the next 19.0 release (19.0.4) and it will be in 19.1 of course.

Audio-wise I'm getting nothing but noise. Is this what happened in earlier error reports?

edit: More research suggests this is actually an issue in Windows too, and disabling audio reverb via the launcher fixes it.

The launcher crashes again on latest Proton experimental 6.3-20210625. Proton 6.3-5 is fine.
steam-312670.log

The regression should be fixed in today's Experimental update, both games were affected.

Can confirm it's working again, thanks!

Getting only a black screen with Nvidia on Plasma Wayland/XWayland with latest Proton Experimental/9.0-4. Not sure if it has ever worked before. Likely Nvidia-specific issue and maybe not even related to Proton itself.

Getting only a black screen even on an AMD GPU. Perhaps its a Wayland issue? My friend is winning an argument. Please help me.
I need this game to work so I can smugly prove that gaming on Linux is totally viable

Hardware Specifications

System Information
CPU: Intel Core i9-14900K (32 logical processors screaming into the void)
GPU: AMD Radeon RX 7900 XTX (24GB VRAM of unfulfilled potential)
RAM: 32GB (none of which Strange Brigade is using because it won't launch)
Motherboard: Gigabyte Z790 AERO G (I don't think that's the problem - Right?)

My Journey of Suffering (Testing Environment)
In my desperate quest to prove he's wrong, I've tested this across with a fresh install:

Bazzite (current - used in Logs) - Nope
Zorin OS - Nada
Ubuntu 25.10 - Nice try
Ubuntu 24.04 LTS - No LTS for Strange Brigade* Yet?

Proton Versions Tested
Every single Proton version that was mentioned in this conversation was tested. All of them. I have no dignity left.

Additional
My friend's "I told you so" grows stronger with each passing day. Time is of the essence.

P.S. - If you fix this, you're not just fixing a proton version. You're settling a bet. You're defending honor. You're proving that a grown adult making the switch to Linux wasn't my first terrible life choice in 2026

No pressure though.

@ThePawlow It's working fine on my end, and was also working fine on august 2025. Currently: 9060 XT, 7800X3D, mesa 25.3.1, linux 6.18.5, Proton 10 and experimental with vulkan and dx12.

From your logs it looks like you're loading from an external partition, what format is it?

Hey @simifor !
Very odd, are you using Wayland?
It's ext4, I just saw that for some reason the partition is called Data (Game Dev). Resulting in an odd mounting point called

/run/media/pawlow/Data\ (Games_Dev)/

Disk model: Samsung SSD 9100 PRO 2TB                
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

@ThePawlow yes, I use plasma wayland. Something you can try to avoid some mounting path woes is setting this as your launch parameter on the game's steam properties window: PROTON_SET_GAME_DRIVE=1 %command%

I've now installed the game along my OS Partition. Still black screen.

/var/home/pawlow/.local/share/Steam/steamapps/common/StrangeBrigade/

EDIT:
Booting with the properties did not fix it neither

PROTON_SET_GAME_DRIVE=1 %command%

EDIT 2:
I wanted to testify, that I run all games from my external disk without issues! 😓

Additionally I wanted to share this picture, the launcher looks different than the one above. So something might changed in the launchers resources too?

Looks like a horribly handled WPF/ WinForms Application 😂

@ThePawlow the launcher looks the same on my end, haven't checked how it looks on windows.
As for things to try

GraphicsOptions.txt
While there aren't many options, it's worth a try replacing your existing graphics options (rename .txt to .ini).
Path is .../SteamLibrary/steamapps/compatdata/312670/pfx/drive_c/users/steamuser/AppData/Local/Strange Brigade/

Replaced with your config - Did not work, sadly

@ThePawlow as you think wayland may be causing issues on your end, have you tried a different desktop environment? I think bazzite omes with SDDM so you should be able to easily switch between desktop environments in the login screen. You can also try installing gamescope and trunning the game with gamescope -- %command%

Hey once again @simifor !

try installing gamescope and trunning the game

It now starts the Launcher in an extra Window with the same graphic artifacts. The game itself just flickers.

have you tried a different desktop environment

I've tried KDE (Brazzite) and GNOME (Ubuntu). With the latest Brazzite Version I cannot change from Wayland back to X11.
I will try CachyOS X11 next - Slowly loosing my mind 😂

EDIT:
Tried latest CachyOS 6.18.6 with X11 and Wayland. Running DX12, Vulkan with and without Gamescope - Same problem!
Now I'm out of ideas.

I tested this on Wayland with RX 7600 on Bazzite (Proton Experimental and Mesa 25.3.3) and Arch Linux (various Mesa and Proton versions), but the only thing I came across was an issue I had with the Vulkan renderer specifically which I've filed here.
