One of my non-Steam games (Ihanashi no Majo) runs perfectly in Desktop mode on the OLED using basically any Proton version.
When I switch to Game mode, however, it’s being forced into a messed-up HDR mode that results in the game being hideously over-saturated. I can’t even tweak the color balance manually, since that slider only applies to SDR.
Is there some sort of launch command option that would enable me to just start the game without HDR?
Going to record my specific “fix” here: I deleted the file libglesv2.dll from my game folder, and now the game launches with colors that aren’t massively over-saturated.
This may be worth trying if anyone encounters this issue with other Tyranobuilder engine based games.
