Bug ID: 509114
Summary: HDR Peak Brightness Clipping
Classification: Plasma
Product: kwin
Version First 6.4.0
Reported In:
Platform: Bazzite
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: colour-management
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
HDR in newer KDE versions supporting the HDR calibration tool clips the maximum
brightness of my monitor (MSI MPG321URX QD OLED)
STEPS TO REPRODUCE
1. configure HDR launch arguments in Steam
2. launch an HDR capable game
3. turn on HDR in game
OBSERVED RESULT
Any bright highlight that should be pushing my monitor's 1000 nits peak gets
dulled, looking washed out like it's getting clipped incorrectly.
EXPECTED RESULT
HDR displaying full range of brightness up to peak 1000 nits
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Bazzite/Cachy both had this issue from my testing, though it
seems to be KDE causing it.
KDE Plasma Version: 6.4 onward
ADDITIONAL INFORMATION
Happens regardless of settings configs in Display Configuration, while previous
KDE versions work after setting reference white 203 nits as maximum SDR
brightness (currently rolled back to KDE 6.3.5)
