Description Gabriel Souza Franco 2020-12-03 14:10:12 UTC 
SUMMARY
At least on my system, minimized windows have no thumbnail. This normally doesn't cause issues, but if compositing is then restarted KWin will spam the logs with the above message until the window is restored again.


STEPS TO REPRODUCE
1. Minimize some window
2. Stop compositing
3. Start compositing

OBSERVED RESULT
Debug log spam.

EXPECTED RESULT
No message.

The warning doesn't exist anymore in the current code base, so this shouldn't happen anymore
