Application: plasmashell (6.2.0) ApplicationNotResponding [ANR]: false Qt Version: 6.7.2 Frameworks Version: 6.6.0 Operating System: Linux 6.8.0-45-generic x86_64 Windowing System: X11 Distribution: KDE neon 6.2 DrKonqi: 6.2.0 [CoredumpBackend] -- Information about the crash: I'm running KDE Neon on a dual monitor setup. I usually leave the computer running overnight, but turn off both monitors for that time. When I turn them back on, there's a plasmashell crash handler waiting each and every time. This has been happening in KDE neon 22.04 as well, but the debug symbols for plasmashell were missing at that time, so it was impossible to send in the report. Now in 24.04 the debug symbols are finally present so a full backtrace is generated. The crash can be reproduced every time. -- Backtrace (Reduced): #6 __pthread_kill_implementation (no_tid=0, signo=6, threadid=<optimized out>) at ./nptl/pthread_kill.c:44 #7 __pthread_kill_internal (signo=6, threadid=<optimized out>) at ./nptl/pthread_kill.c:78 #8 __GI___pthread_kill (threadid=<optimized out>, signo=signo@entry=6) at ./nptl/pthread_kill.c:89 #9 0x00007b12b244526e in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #10 0x00007b12b24288ff in __GI_abort () at ./stdlib/abort.c:79 Reported using DrKonqi

I've just observed that the crash occurs specifically when(ever) I turn off the primary monitor. In such a case, the windows from the primary screen try to shuffle onto the secondary screen and at that moment the drkonqi crash dialog gets displayed on the secondary screen, too. The crash does happen with the secondary screen off, too. If it is relevant in any way, both my monitors are using 1920x1200 resolution, the secondary screen is above the primary screen. I have an AMD Ryzen 7 5700X CPU and an AMD Radeon RX 6600 GPU; the primary screen is connected to the HDMI port, the secondary screen is connected to the DP port.
