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 SOFTWARE/OS VERSIONS Operating System: Kubuntu 25.04 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.3 Kernel Version: 6.14.0-15-generic (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i5-1155G7 @ 2.50GHz Memory: 7.5 GiB of RAM Graphics Processor: Intel® Iris® Xe Graphics Manufacturer: LENOVO Product Name: 82H7 System Version: IdeaPad 3 14ITL6 Linux/KDE Plasma: yes ADDITIONAL INFORMATION it's a bit rare to get the bug, but it will definitively appear in that range of time. I'm also based in the bug #451825, wuch it seems to have a similar problem
Created attachment 181407 [details] the ghost window at the moment of closing the app
It does indeed seem like the same issue as Bug 451825, or a re-occurrence of it.
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!
