Application: plasmashell (5.24.4) Qt Version: 5.15.2 Frameworks Version: 5.90.0 Operating System: Linux 5.14.21-150400.24.11-default x86_64 Windowing System: X11 Distribution: "openSUSE Leap 15.4" DrKonqi: 5.24.4 [KCrashBackend] -- Information about the crash: - Unusual behavior I noticed: Sometimes the screen freezes completely while multimedia is in use (YouTube, but also DVD films occasionally). The cursor can sometimes be moved; after a time, this stops too, or the cursor cannot be moved right from the start of the phenomenon. The clock widget freezes, work surfaces (I have 4) cannot be changed, there is no reaction to keyboard attempts to restart. I am forced to reset and reboot, which always works fine. The problem then does not occur for quite some time. A secondary problem which may be associated is that the screen occasionally goes black under the same circumstances, as far as I can tell, but only for a second, then everything is there again. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault [KCrash Handler] #4 QVector<int>::isEmpty (this=<optimized out>) at

Plasma doesn't have the power to directly generate these kinds of symptoms; the only way I could think of is if it's rapidly consuming all system memory, which would make everytihng hang and eventually things would start to crash. Can you see if that's what's happening? If it's not, then the only remaining culprits would be KWin, your graphics drivers, or the X server. What graphics hardware do you have?

Hmm, tall order for me. I can say at the moment that I have AMD Radeon, KAVERI is the graphics processor. OS: openSUSE Leap 15.4 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.14.21-150400.24.11-default (64-bit) Graphics Platform: X11 Processors: 2 × AMD A6-7400K Radeon R5, 6 Compute Cores 2C+4G Memory: 6,7 GiB working memory Graphics processor: AMD KAVERI My system monitor does not indicate that Plasma is using any more memory than usual, and I do not expect it to. It may well be the X server, or KWin, or the graphics drivers, but I don't know. Possibly Firefox is causing trouble, or an add-on to the same (but that is not a KDE problem, clearly). Funny thing too, a simple reset and the whole thing boots normally. The working memory (or whatever it is called) has a max of 6.7 GB, around 3 is being used, so I assume the problem is not there. I had to clean up my repositories, but it is not clear whether this might have (or have had) an effect. So all that is probably of no help. My apologies if I have reported a bug and there isn't one. The system seemed to 'think' there was, and the wizard appeared, so I went ahead. Many thanks nonetheless! D. Fear
Are you saying the problem stopped happening?

I cannot say yet - it has not occurred since I cleaned up the repositories, but since I do not know what is involved, I must run a practical test this evening (i.e. try to 'overload' with multimedia and Firefox and see whether the problem repeats itself). A console enquiry showed that amdgpu is installed and running, so it should not really be a driver problem (famous last words!). I will let you know asap, whether results are negative (which I hope) or positive (in which case I am a bit stuck). Thanks very much! If there is any other information you might need, just let me know and I'll try to supply it.

The problem still occurs - something is using the hard disk memory to the point of blocking other processes. This time it was coming out of stand-by. Nothing reacted, so again a cold reboot. This appears to be a problem with something else, hardly likely to be a KDE matter. I am still trying to get to the bottom of it. The wizard was possibly triggered because Plasma was affected, rather than being the source of any problem.

I have now (seemingly) narrowed the problem down - there is some kind of conflict caused by Firefox additions, so definitely not a KDE Plasma problem. Again, my apologies for the mistaken bug. KDE remains a stable and reliable desktop - as expected! Yours, D. Fear
Great news! Thanks for following up.
