Application: kwin_wayland (6.5.0) ApplicationNotResponding [ANR]: false Qt Version: 6.10.0 Frameworks Version: 6.19.0 Operating System: Linux 6.17.5-arch1-1 x86_64 Windowing System: Wayland Distribution: Arch Linux DrKonqi: 6.5.0 [CoredumpBackend] -- Information about the crash: Dual monitor setup, wayland compositing, with displays turned off by power management at lock screen. Pressing a key activates displays and shows login screen, but with password field only on one screen (I think now it should appear on both, so possibly something has already gone wrong). On logging in have desktop on both monitors, but some applications have crashed, and remaining windows have all been moved to one display. Kwin has crashed. The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin_wayland), signal: Aborted Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>} warning: Can't open file /memfd:JSVMStack:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:JSGCHeap:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:/.glXXXXXX (deleted) during file-backed mapping note processing warning: Can't open file /memfd:wayland-shm (deleted) during file-backed mapping note processing warning: Can't open file /memfd:gdk-wayland (deleted) during file-backed mapping note processing warning: Can't open file /memfd:wayland-cursor (deleted) during file-backed mapping note processing warning: Can't open file /memfd:unknown-usage:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:xwayland-shared (deleted) during file-backed mapping note processing warning: Can't open file /memfd:JITCode:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:kwayland-shared (deleted) during file-backed mapping note processing [New LWP 1157] [New LWP 1175] [New LWP 1187] [New LWP 1208] [New LWP 1188] [Thread debugging using libthread_db enabled] Using host libthread_db library "/usr/lib/libthread_db.so.1".
