Hello @Marks20125, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/9595#issuecomment-5847700907.
Hello @Marks20125, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to [#9595 (comment)](https://github.com/ValveSoftware/Proton/issues/9595#issuecomment-5847700907).
I assumed I had to create a different issue as my issue has nothing to do with crashing, sorry 😅

As you can see, random textures start flashing on the screen
Reproduction
While it is pretty random, I've noticed it almost always happens on spirit-related stuff, like the ability shown in the video, but it happens on other cases too. The bug happens regardless of whether upscaling or framegen is on or off. I tried asking other players if this also happens on Windows, assuming it was a proton bug, but they told me it didn't happen on windows and, apparently, not on Linux either. Now, I have no idea where the issue could be, as it doesn't seem to be related to dlss/fsr, but it looks like it isn't a game bug as other players aren't experiencing it
