Penumbra: Overture ingame enviroment not displaying on Proton version
Unfortunately the native version renders correctly but has a library issue that has started to cause the game to crash on newer distros part way into the game. Users would like to run the windows version on Proton but that has issues were the screen is black in game when Post Processing Effects is turned on and the only thing that can be seen is the mouse icons when they are moved over interactive objects.
I'm attaching a trace from the native and windows version. There is some extra errors thrown in the windows version where those invalid calls have been removed in the linux version but editing mesa to silently ignore the invalid calls rather than throwing an error doesn't get us any further.
