Bug ID: 443027 Summary: Screen elements are reset after screen wakes from off Product: kwin Version: 5.22.5 Platform: unspecified OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: yosukematsum...@gmail.com Target Milestone: --- SUMMARY Desktop computer's monitor/screen turns off (either manually, or due to sleep timer). When the screen is turned back on, the desktop is "reset" - Panel has disappeared, desktop wallpaper reset to default, and existing windows are moved/resized. STEPS TO REPRODUCE 1. Boot up & Log in (Wayland session) - does not reproduce in X11. 2. Turn off the screen. Note - just the screen power needs to be turned off. Does not require computer to go into suspend mode. Can be done in multiple ways - all produce the error: a. In System Settings > Power Management > Energy Savings > Button Events Handling > Set When power button is pressed "Turn off screen". And then press the power button on the computer. b. Press the power button on the monitor (or pull the power cord to the monitor). c. Wait for system to sleep and causing monitor to power off. 3. Wait 30s (I haven't determined a minimum time required, but sometimes it doesn't happen if the screen is turned back on quickly after turning off). OBSERVED RESULT Screen is "reset". The side panel (only panel) is gone. The desktop background/wallpaper is set to default. The open window is moved to upper left and resized. See attachment: After Screen On.png EXPECTED RESULT Screen should appear exactly the same as before the screen is turned off.
