Next time it happens can you get the error it's printing via journalctl --user -u plasma-kwin_wayland -r It's throwing an error here #4 0x00007f31442927ed in QMessageLogger::fatal(char const*, ...) const () from /usr/lib/libQt6Core.so.6 to stderr, but we have no idea what, which makes this unactionable Created attachment 182986 [details]
