Debug log of plasmashell
SUMMARY
After a certain amount of time plasmashell seems to hang for unknown reasons.
This means that no interaction with the panels is possible anymore and the
desktop doesn't update (only the windows rendered above are visible).
Certain features of the desktop are functional when the hang occurs. This
includes the task switcher and global shortcuts like for invoking krunner or
the task manager. But sometimes, krunner is affected as well. Sometimes it seem
to affect the stability of unrelated applications (Chromium browser, Elektron
Apps) as well.
This behavior is present at least since March 2020.
STEPS TO REPRODUCE
Sadly I don't know how I can reproduce this behavior. But it seems to be
related with some kind of user activity.
It's also my work system so I don't want to tinker too much. I tried my best to
give you as much information as possible.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: NixOS 5.4.50 20.09pre233323.dc80d7bc4a2 64 bit
(available in About System)
KDE Plasma Version: 5.17.5
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.7
The hardware is a Thinkpad T470p with Intel graphics. There's always plenty of
RAM and CPU available. I'm always using one or two external displays.
ADDITIONAL INFORMATION
Once I kill/restart the plasmashell process, everything is functional again.
I tried to turn on some logging but there are no traces of an error for me. I
attached the output of the following command line until the hang behavior
occurs:
env QT_LOGGING_RULES="* = true; qt.scenegraph.* = false; qt.quick.hover.trace =
false; qt.qpa.events = false; qt.qpa.input.* = false; qt.quick.mouse.target =
false;" plasmashell --replace 2>&1 | gawk '{ print strftime("[ %T ]%t") $0 }' >
plasma_report.log
I filtered some very noisy events since they seemed to be rather unrelated.
