Description Till Schäfer 2021-10-29 15:22:06 UTC

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.

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?
