Bug ID: 499926
Summary: "Preffer color accuracy" Freezes plasma when set and
bricks it
Classification: Plasma
Product: kwin
Version: git-stable-Plasma/6.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: colour-management
Assignee: kwin-bugs-n...@kde.org
Reporter: qua...@proton.me
Target Milestone: ---
SUMMARY
When i set "Color accuracy" to "Preffer color accuracy" the system immediately
freezes. And when i force shut down and i try to log in to the Wayland session,
it freezes before the plasma splash screen. So it is basically a black screen.
And in order to fix it, i had to log in to the X11 Session (tty did not work
for some bizzare reason), and edit the file ".config/kwinoutputconfig.json" and
change "colorPowerTradeoff" to "PreferEfficiency", and a reboot later; it
started fine.
STEPS TO REPRODUCE
1. Open system settings.
2. Go to the display settings section.
3. Set "Color accuracy" to "Preffer color accuracy".
OBSERVED RESULT
System freezes.
EXPECTED RESULT
System doesn't freeze.
