When using KWins show desktop shortcut, it happens sometimes, that the windows cannot be restored using the shortcut a second time. In this case, it is also impossible to restore the windows by using the task manager or the Alt+Tab shortcut. The applications can only be closed via task managers right click or shortcuts. This happens not often, but a few times a month for me. It happens on different machines using wayland and X11. Operating System: Gentoo Linux KDE Plasma Version: 5.23.2 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Kernel Version: 5.14.14-gentoo (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-3770 CPU @ 3.40GHz Memory: 30.8 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4000
I can reliably reproduce the bug by opening multiple windows / applications and repeating the shortcut very fast. Maybe the shortcuts executions are overlapping and causing some inconsistent state?
