Application: kwin_wayland (6.4.5) ApplicationNotResponding [ANR]: false Qt Version: 6.9.2 Frameworks Version: 6.18.0 Operating System: Linux 6.16.10-arch1-1 x86_64 Windowing System: Wayland Distribution: Arch Linux DrKonqi: 6.4.5 [CoredumpBackend] -- Information about the crash: My laptop is always using an external monitor using a n usb-c hub with hdmi outport. When I was trying to lock the screen after about an hour I as not using it, the system was not responsive, I finally unplugged the usb-c and heard a "pling" sound. After that the system was responding again and this kwin crash appeared. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: KWin (kwin_wayland), signal: Segmentation fault Downloading separate debug info for /usr/bin/kwin_wayland... warning: Can't open file /memfd:JSGCHeap:QtQml (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:wayland-cursor (deleted) during file-backed mapping note processing warning: Can't open file anon_inode:i915.gem 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:JSVMStack:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:kwayland-shared (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-shm (deleted) during file-backed mapping note processing warning: Can't open file /memfd:unknown-usage:QtQml (deleted) during file-backed mapping note processing [New LWP 1049] [New LWP 1079] [New LWP 1063] [New LWP 1080] [New LWP 1094] [New LWP 1093] [New LWP 1095] [New LWP 1096] [New LWP 1081] [New LWP 1092] [New LWP 1083] [New LWP 384204] [New LWP 1836] [New LWP 384205] [New LWP 1881] Downloading 9.88 M separate debug info for /usr/lib/libc.so.6...
