Bug ID: 466355
Summary: plasmashell service reports multiple child processes
Classification: Plasma
Product: plasmashell
Version: 5.27.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-performance
Assignee: plasma-b...@kde.org
Reporter: q9hc2...@duck.com
Target Milestone: 1.0
SUMMARY
***
Whenever I launch a program from the application menu they automatically get
added to the plasmashell service status. Consequently increasing the memory
usage of the plasmashell service. If for example plasmashell crashes it takes
down any subprocesses with it including FF, Sublime or any other open program.
The question is whether this design is normal behavior, or something changed as
part of the Linux Kernel ?
If I launch FF or any program directly from the terminal then the plasmashell
service status does not get populated with additional processes.
I can understand why FF has these processes as these are controlled via
"dom.ipc.processCount.webIsolated", but the above question remains.
