HDR
Could you try running the game in a gamescope session for comparison? So
> gamescope -e --hdr-enabled -- steam -gamepadui
from a tty
Curiously steam crashes when I try that :S On the steam deck the game works as expected though. (In reply to Harald Sitter from comment #4) > On the steam deck the game works as expected though. Ok, then it might be a bug in KWin. Can you start gamescope nested with WAYLAND_DEBUG=1 and give me the log for that? Would be interesting to know what colorspace the game is using Created attachment 180906 [details]
wayland_debug log
Attaching the log. Towards the end I'm disabling&enabling HDR for good measure.
Alright, it does set the surface to BT2020PQ:

Only thing that's a wrong is that it doesn't set any HDR metadata, which may make KWin do much more aggressive tone mapping than necessary. I see that was recently fixed in gamescope, could you try again with the latest version? Gamescope git master seems to work fine for me in other games at least (besides an annoying mouse input issue, but that's unrelated)
Currently can't be tested because gamescope just crashes out https://github.com/ValveSoftware/gamescope/issues/1796 Setting needsinfo state so the bot can remind me to check in a couple weeks. 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days.

Still blocked upstream. I did leave some more info that hopefully should help resolve the upstream problem.

Still no upstream fix in sight. I'll reopen whenever that happens and the colors are still off. |
