Bug ID: 513978
Summary: HDR broken brightness and black levels
Classification: Plasma
Product: kwin
Version First 6.5.4
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: colour-management
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
On games like TLOU 1 brightness is broken with HDR on,
KWIN_DISABLE_TONEMAPPING=1 does help a little, still looks off, on
DOOM Eternal (vulkan app) blacks look crushed with HDR on, disabling
tonemapping doesn't help.
I'm almost certain this happened due to the recent plasma upgrade, pacman.log
shows kwin (6.4.5-4 -> 6.5.4-3), plasma-desktop (6.4.5-4 -> 6.5.4-1) because i
always tried using the LTS kernel instead of mainline, downgrading mesa and
proton to a much older version and that didn't change anything.
This problem happens either with wine wayland or gamescope.
STEPS TO REPRODUCE
Launch TLOU 1 and check the brightness options, setting to HDR makes it look
washed out
Or launch Doom Eternal, should look terrible, kinda like posterization
