Created attachment 157202 [details] system journal SUMMARY System is a laptop with an external monitor attached on HDMI port; I was not at the computer when the crash happened, and certainly wasn't interacting with it. When I came back to it I found that kwin_wayland had crashed and restarted, so I'm afraid I can't provide exact events leading up to the crash, perhaps it has to do with screenlocking. But I've attached core dump, back trace & libs info as found by drkonqi and system journal around the crash. STEPS TO REPRODUCE unsure OBSERVED RESULT kwin_wayland crashed EXPECTED RESULT kwin_wayland should not crash SOFTWARE/OS VERSIONS Operating System: Fedora Linux 37 KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.14-200.fc37.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 6850U with Radeon Graphics Memory: 14.4 GiB of RAM Graphics Processor: AMD Radeon Graphics 680M
