Created attachment 151976 [details] Output of dmesg right after crashing All open windows suddenly close seemingly out of nowhere. Also if I use CLion from JetBrains toolbox, the same exact thing seems to happen almost immediately. Looking at the output of dmesg, I notice a segfault right as the crash happens '[ 47.207222] kwin_wayland[748]: segfault at 10 ip 00007f4e93bb2994 sp 00007ffeab7c9788 error 4 in libkwin.so.5.25.5[7f4e93a51000+297000]' Only surefire way to reproduce this bug is to open JetBrains toolbox, and launch CLion and start editing a file. Otherwise this seems to happen at random. Operating system: Arch Linux KDE Plasma Version: 5.25.5 KDE Frameworks Version: 5.97.0 Qt Version: 5.15.6 Graphics Platform: Wayland
