Bug ID: 501622
Summary: SDR black has faint glow
Classification: Plasma
Product: kwin
Version: 6.3.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: colour-management
Assignee: kwin-bugs-n...@kde.org
Reporter: fk-kde-b...@ubermail.me
Target Milestone: ---
SUMMARY
On my OLED screen I use as much black as possible (wallpaper, dark mode). With
kwin-6.3.3 I noticed that in SDR mode my "solid color: black" wallpaper appears
to have a faint gray. Switching to HDR mode has proper true black again.
This is with no ICC profile configured and "Prefer efficiency" set. Though
toying with either didn't appear to change anything.
Reminds me of a https://bugs.kde.org/show_bug.cgi?id=494854 - except likely no
vk_hdr_layer involved.
STEPS TO REPRODUCE
1. Own an OLED
2. Display black in SDR mode
3. Turn down external light sources in your room
OBSERVED RESULT
See the whole screen faintly glowing
EXPECTED RESULT
Only the mouse cursor should emit light
