Maybe it's because we don't use the same variant of Proton ?
My default is proton-cachyos and I usually use GE when I have issues.
Honestly I'm not really willing to use GE as a default. Proton-cachyos is, if I understand correctly, a proton version optimized specifically for my OS and is pretty much based on similar proton-experimental upstream.
For now HDR support is not really worth switching things up for me. Even on Windows honestly I didn't see a difference on my pretty high end OLED ultrawide monitor.
I will try again later but for now if it doesn't work fine with my DE or my proton version of choice I don't think it's really worth the complexification.
