Bug ID: 461886
Summary: Waking screen causes application windows to disappear
Classification: Plasma
Product: kwin
Version: 5.26.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal

System log from the timeframe of screen wake
SUMMARY
This issue occurs after waking the screen after it has turned off (due to
Screen Energy Saving) - *not* from Suspend session (when manually putting
computer to sleep). Some application windows (though not always all) seem to
disappear. The application is still running and its icon is still in the Task
Manager. However, clicking the application icon in the Task Manager does not
bring the window into view.
I end up needing to close the windows from the Task Manager (window preview
pane shows blank window as well). Then I can re-launch the application.
I see in the system log (attached), that there is this message from the time
when I wake the screen:
kwin_wayland[14813]: libkwinglutils: Invalid framebuffer status:
"GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"
STEPS TO REPRODUCE
1. In System Settings, Power Management, Energy Saving, enable Screen Energy
Saving and set time to some value < Suspend Session time.
2. Wait for screen to turn off as per time set in step 1
3. Wake the screen by pressing key on keyboard
OBSERVED RESULT
Some windows that were open and visible before the screen turned off - such as
Konsole - are no longer visible. However some other windows are unaffected -
such as Firefox. I'm unable to find a pattern as to which windows will
disappear and which won't, but Konsole seems to be reliably reproducible.
EXPECTED RESULT
All open and visible windows before the screen turned off should be present
when the screen turns back on.
