Bug ID: 465603
Summary: Plasmashell stresses CPU then crashes
Classification: Plasma
Product: plasmashell
Version: 5.26.90
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: td21rz...@mozmail.com
Target Milestone: 1.0
SUMMARY
During normal usage (playing a game, writing documents, etc.) my Ryzen 7 7700X
temperature spikes to its maximum for a while until the "plasmashell" process
eventually crashes. Subsequent starts of plasmashell, either when it respawns
on its own or using "kstart5 plasmashell" if it doesn't, makes it exhibit the
same behaviour eventually.
CPU usage remains at approximately 25% when plasmashell causes the CPU to work
a sweat.
When plasmashell crashes, CPU temperature returns to normal.
This has only happened with the package "plasma-desktop 5.26.90-2" from the
KDE-Unstable repository on Arch Linux.
Unable to test with X11 at the moment, and would appreciate if someone with
similar hardware would be able to do so.
STEPS TO REPRODUCE
1. Install plasma-desktop 5.26.90-2 on Arch Linux
2. Keep using the computer like you normally would
OBSERVED RESULT
The plasmashell process causes the CPU to work really hard (but not with high
usage!) and eventually crashes.
EXPECTED RESULT
plasmashell does my bidding without causing high CPU temperatures or crashing
SOFTWARE/OS VERSIONS
Linux: 6.1.9
KDE Plasma Version: 5.26.90
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8
ADDITIONAL INFORMATION
Upload backtrace after posting this. In the backtrace, I start plasmashell via
gdb and play a game until it crashes, in which I save the log and quit gdb.
Have tried running minimal amounts of applications and waiting, then seen the
crash happen regardless. Not sure what sort of config files would help here, so
please let me know and I'll upload them ASAP.
