Created attachment 113544 [details] KWin backtrace This is one seg fault I found in my coredumps, which happens through a late call through PoitnerInputRedirection while the app is going down. The workspace instance is already destroyed.
Core was generated by `/usr/bin/kwin_wayland --xwayland --libinput --exit-with-session=/usr/lib/x86_64'.
