Bug ID: 499934
Summary: Plasma 6.3 broke HDR brightness
Classification: I don't know
Product: kde
Version: unspecified
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: minc...@protonmail.com
Target Milestone: ---
SUMMARY
The SDR brightness setting is also changing the brightness of HDR content
instead of HDR content displaying at the highest brightness/default monitor
brightness. To get the full brightness for HDR, you have to turn the SDR
brightness all the way up to 500 nits otherwise HDR is dim. This makes SDR
content too bright.
STEPS TO REPRODUCE
1. Update to 6.3
2. Enable HDR
3. Open HDR content/game
OBSERVED RESULT
HDR will be at SDR setting for brightness, rather than peak brightness.
EXPECTED RESULT
HDR should be following the monitor's max brightness/default brightness for HDR
mode.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
