heaptrack screenshot
SUMMARY
***
I noticed plasmashell was, apparently, using more than 20 gigabytes of memory.
I did a heaptrack capture for five minutes. In that time plasmashell allocated
another 1.3 gigabytes. I've attached a heaptrack screenshot and will attempt to
attach the log aswell.
***
STEPS TO REPRODUCE
1. I've yet to consistently reproduce it. It happens from time to time.
OBSERVED RESULT
Plasmashell using all available memory and the system starts to swap.
EXPECTED RESULT
Plasmashell using less than 150 megabytes of memory.
SOFTWARE/OS VERSIONS
Linux: 5.15.38
KDE Plasma Version: 5.24.5
KDE Frameworks Version: 5.94.0
Qt Version: 5.15.3
ADDITIONAL INFORMATION
I'm running plasma wayland with an AMD RX570 and not sure whether culprit is
plasmashell, qt, mesa or amdgpu because the following shows up, alot, in
wayland-session log:
"...
