-- Information about the crash:
While searching for an application window, it was Alacritty, with the "toggle
overview" window management feature kwin stopped at the "ala" part and then
crashed/restarted. I had several windows open (multple browser windows,
thunderbird, 5-6 alacritty terminal windows, steam and maybe even mpv) and when
I tried to search for one of them the crash happened.
I have tried to reproduce it just by openning several background windows and
several terminal windows and searching for one of them, but I can't reproduce
it.
The reporter is unsure if this crash is reproducible.
