Bug ID: 465403
Summary: Blank screen when resuming from sleep or hibernate or
when TV has been off for a while
Classification: Plasma
Product: kwin
Version: 5.26.5
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
Blank screen when resuming from sleep or hibernate or when TV has been off for
a while
STEPS TO REPRODUCE
1. Boot
2. Login
3. Sleep or Hibernate
4. Wait for TV to go a sleep or switch off (Samsung Neo QLED QN90B 43")
5. Resume
6. You reached the failure state
OBSERVED RESULT
The screen is white or flickering between white and rendering the lock screen.
Login works. Typing in kwin_x11 --replace sometimes works and then the system
can be used again.
Most of the times the system does not recover and a reboot is required.
I used KDE Connect to unlock and execute kwin_x11 --replace also.
This sometimes also works as a work arround.
EXPECTED RESULT
Rendering the lock screen normally and resume the system in a usable state.
