[1.0.2][Linux] Does not run with proton | Shapez 2 | Page 1

Running on Linux (arch) fails in a crash. With standard Steam proton it just crashes back to the desktop. With different proton versions I at least get the game started but get the blow error.

I am not on Valve hardware.

Version 0.9.9 works fine.

Hello @soft musk

I see a double error in the log, and want to first recommend using Direct X 11 instead of Vulkan, there has been increased stability using DX 11 (known bug with Unity interfering with the driver on some versions). If that fixes the first issue, there may be a second issue occurring. If you are still crashing would we be able to get an updated player.log file?

Thank you,
Josh

If i start the game with the default proton (like just download) I do not even get the selector screen, It crashes before it.

soft musk Apr 23, 2026, 5:44 PM

With proton 10.0-4 I get the selector and can at least select dx and it starts. The default or vulkan options both fail

slender elk Apr 23, 2026, 6:29 PM

#

Proton will force Vulkan, and looking more into this, we can try forcing DX 11 using the launch command -force-d3d11 in the Proton launch option. Please let me know if that changes any of the behaviors.

Thank you,
Josh

If I add the parameter in the steam settings (and select the default proton) it still crashes before even starting the game. I'm not sure steam passes it through. I have to check if I can easily launch it outside of steam.
Selecting Proton 10.x manually works fine though.
Then I can also select the api directly in steam

So proton 10.x is making it work or you are still having issues with it crashing?

Even with the current version of the game it crashes without 10x. I did not debug it further to see if it is Vulkan or driver or similar. I also did not try different proton versions.

--disable-store-sdk launch argument prevents game to launch when preload intro has not yet been seen
Done • Priority: Highest • Fix: 1.0.3 release (Hotfix 1) • Game: 1.0.1-rc1 • Resolution: Fix Verified

Using the --disable-store-sdk launch argument prevents shapez 2 from launching when the preload intro has not yet been seen, such as on a first launch. The failure is caused by a graphics initialization check for Steam Deck that incorrectly assumes the Steam SDK is initialized. Clearing the settings folder and launching with --disable-store-sdk reproduces the issue. The game should launch successfully with this argument without depending on the Steam SDK during graphics initialization. A fix ...

[Linux] Title always exits shortly after starting it
To Do • Priority: High • Fix: None • Game: 1.0.3-rc3

On Linux (Ubuntu and Arch), shapez 2 crashes shortly after launching, though not 100% reproducibly. The crash appears related to native resolution, as it can be worked around by using a non-native resolution or by manually creating a display.json file with a specific resolution and windowed mode. The log shows a fatal runtime error in the Mono runtime or native libraries. Expected behavior is that shapez 2 starts successfully every time without requiring manual configuration changes.

[Linux] The title will end straight after starting a few times before starting properly
To Do • Priority: Medium • Fix: None • Game: 1.0.3-rc3

On Linux (Ubuntu, Arch), shapez 2 crashes immediately after launching multiple times before eventually starting properly. The issue is triggered by a fatal runtime error in the Mono runtime or one of its native libraries, with native fault reporting also failing, which leaves some diagnostic information unavailable. The expected behavior is that shapez 2 should start properly on the first launch attempt.

Crash on startup
Done • Priority: Medium • Fix: Version 0.0.9 • Game: 24.2.2 • Resolution: Won't Fix

shapez 2 crashes on startup with a SIGSEGV error when running natively on Linux, likely triggered by recent OS package updates (such as mesa, mutter, vulkan-loader, or xwayland). The game was previously working but newer package versions broke compatibility. Running under Proton appears to work as a workaround, though sound issues were also reported. The crash occurs in native code before the menu is displayed. This is not something the development team can fix on their end, so using Proton i...

Shapez 2 can crash when switching graphics settings while using Linux.
To Do • Priority: Critical • Fix: None • Game: 0.1.1

shapez 2 can crash or become unstable on Linux when changing and applying graphics settings such as resolution and window mode. This occurs when users navigate to Settings > Graphics and apply changes. Additionally, some users experience crashes at startup, potentially due to the application attempting to apply outdated graphics settings from a previous version before the settings refactor in rc1. The expected behavior is that the game remains functional and stable after applying graphics cha...

Game crashes when using a RX6600XT or RX6600 when using Vulkan
To Do • Priority: High • Fix: Probably Never • Game: 1.0.0-beta2

shapez 2 crashes when reaching the main menu while using the Vulkan graphics API on AMD GPUs, including the RX 6600, RX 6600 XT, RX 9060 XT, and RX 5700 XT. The crash is triggered by launching the game with Vulkan, particularly with graphics settings above low. This appears to be a regression introduced in Unity 2022.3.62f2, as builds using the older Unity 2022.3.42f1 do not exhibit the crash. Since Unity no longer releases new LTS updates for the 2022.3 series without an enterprise license, ...

I am closing this bug report.
No one else is reporting issues with proton not working and you are getting this running with Proton 10+
But if you have any further information reply to me. i.e. force a ping?
Also someone said something about something called gamescope causing issues. If you are running that, try turning it off.
