@forge161 the game looks normal to me on proton 10 and experimental, I tried on an amd desktop and nvidia laptop both with plasma wayland (which I think is what you're using). Do you remember if you changed any settings on plasma that might affect colors in some way? Have you checked other desktop environments to see if something similar happens in them?
@simifor I haven't tried other desktop environments, and I haven't changed any color settings. Make sure you compare the the main menu of the first game between latest Proton and Proton 9.0-4. As soon as I switch back to 9.0-4 the color issue is fixed without me changing anything else.
Hi @forge161, for me happened the same. I have a RTX 4070 TI Super and Proton 10 shows weir colors, like 16 bits. Also when I have changed to Proton 9.0-4 colors are fixed.
