Bug ID: 469098
Summary: Waking from screen off leads to a white screen.
Classification: Plasma
Product: kwin
Version: 5.27.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: f.pr...@numrax.de
Target Milestone: ---
SUMMARY
After waking the screen from a power-save screen-off event, the screen wakes to
a white screen. Sometimes, very rarely, the system wakes to a white screen
alternating with the original screen content. It alternates white/content with
every keystroke and/or mouse movement.
"ALT-F2 & kwin --restart" returns to a non-flickering, "usable" state, with all
previous windows and content lost. If Akonadi (bug #468568) doesn't crash.
STEPS TO REPRODUCE
1. Configure screen sleep in the Energy Saving settings (or Activity Power
Settings)
2. Sleep
3. Wake
OBSERVED RESULT
White screen, loss of previous state.
EXPECTED RESULT
Correct waking of the system, with the previous state and work restored.
