Created attachment 154693 [details] Kwin X11 termination SUMMARY Kwin in X11 session terminates with "The X11 connection broke: I/O error (code 1)" message in syslog. This usually happens once in 2-3 days of active work on the PC. X11 does not crash, nor any other software using X11, only kwin terminates (and not crashes either). STEPS TO REPRODUCE 1. Run Plasma session in X11 2. Work for 2-3 days 3. See kwin termination OBSERVED RESULT Kwin terminates, window titles and utility buttons disappear, everything other continue to work. EXPECTED RESULT Kwin does not terminate. SOFTWARE/OS VERSIONS ADDITIONAL INFORMATION No crash dumps, no crash records in dmesg, no suspicious records in journalctl. Latest log records: $ journalctl -b -1 --user -u plasma-kwin_x11.service дек 19 16:23:18 val kwin_x11[1927]: The X11 connection broke: I/O error (code 1) дек 19 16:23:18 val kwin_x11[1927]: X connection to :0 broken (explicit kill or server shutdown). дек 19 16:23:18 val systemd[1747]: plasma-kwin_x11.service: Consumed 26min 12.525s CPU time.
