I've been playing Black Ops 3 through Proton just fine until a few days ago some of the textures mainly transparent ones like glass turned bright white, It happened after I switch from running the game on GE-Proton 8-9 to 8-25.

I've tried everything I could think of, switching back to 8-9 and regular Proton Experimental, manually clearing the vulkan cache and even reinstalling the whole game after making sure no files were left over.

Any ideas how to fix this? I am using an Nvidia GPU, which is normally the cause of my problems...
