Untrue.
Edit: I effortlessly use it on Bazzite. What's the issue you guys are having?
You want to explain? Because the last time I checked getting HDR to work with games is a huge hassle.
with KDE and Wayland i have no issues, using Steam launch parameters:
PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1Linux 6.18
AMD Radeon 9070XT
Mesa 25
Doesn’t this require you to also be on plasma 6.4?
Using proton wayland also breaks steam input, which can be deal breaker.
Actually very true.
Kde has good hdr with Wayland but a lot DEs still are very much a crapshoot, yes
Getting it to actually work with games is still a crapshoot, though.
Plasma 6.5 has broken tonemapping both with gamescope and proton wayland (which breaks a bunch of other things to boot). The fix was merged just a couple of weeks ago.
To be fair, HDR gaming is pretty bad on Windows, too. (Unless - so I heard - you use RTX HDR, which is still a workaround AND you need a new-dish NVIDIA card, which I don't have.)
