Created attachment 142690 [details] coredumpctl SUMMARY Kwin_wayland segmentation fault. STEPS TO REPRODUCE 1. Difficult to determine but I think it may be related with the use of secondary display when restoring the session after suspend, but not happening always after restoring... OBSERVED RESULT [21797.442029] kwin_wayland[1080]: segfault at 10 ip 00007fcfffa0f670 sp 00007ffec956b8e8 error 4 in libKWaylandServer.so.5.23.1[7fcfff9bc000+d5000] SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.23.1 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Kernel Version: 5.14.13-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz Memory: 15.4 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics

Created attachment 142705 [details] coredump-KWinWaylandDrmBackend.txt Once again, maybe different issue as this coredump is quite different now. Secondary display is wrong: mouse pointer in secondary screen has vertical offset (of +357), and secondary screen has bad dimensions: 1280x720 when it must be 1920x1080.

Will recompile asap

Created attachment 142718 [details] Desktop screenshot, and real screenshot This screenshot explains the situation, also there's the pointer offset, as cursor points below it appears.
