Description StanPilot11 2025-05-17 01:21:17 UTC

SUMMARY
after prolonged use, the application window displayed on the desktop will become transparent and freeze, not responding to any events, and it becomes like a ghost window. it happens on almost all windows (GNOME based apps too), and it happens on X11 and Wayland, both being a bit rare to happen

STEPS TO REPRODUCE
1. leave a window for a long time (between twenty minutes and two hours)

OBSERVED RESULT
after closing or minimizing the window, it appears another one, with no response, unable to interact with it and without an error message

EXPECTED RESULT
same as before

It does indeed seem like the same issue as Bug 451825, or a re-occurrence of it.

Comment 3 John Kizer 2025-05-23 05:27:55 UTC

Hi - just to check, when this issue occurs with a minimized application, is the application itself still running - even if it's invisible, in the background? And, are you able to restore the application?

Thanks!
