Bug ID: 386834
Summary: Plasmashell 100% cpu always following filescan using
application "SourceGuardian"
Product: plasmashell
Version: master
Platform: Debian stable
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: v...@vark.nu
CC: plasma-b...@kde.org
Target Milestone: 1.0
I am aware of multiple bugs showing 100% utilisation after various triggers,
with various fixes (turning off animated icons etc). No luck following any
current advice.
I can however trigger a long delay in Plasmashell reliably using the
"SourceGuardian" application - whenever this starts a filescan of a project (on
startup, or via a manual trigger) Plasmashell hits 100% utilisation and becomes
unresponsive to any user input for several minutes. I can click to other
applications that are already on screen, use them, and access the filesystem
etc, but cannot open new applications from the taskbar (alt-F2 still responds
and I can start a shell). After several minutes, it does then eventually
respond and works normally until the next filescan.
Reported also to the SourceGuardian application vendor with no real success or
interest in resolving however.
Happy to provide testing in order to help troubleshoot, as aware that a lot of
the existing bugs raised for this do not have a reliable trigger method.
Reproduced on Debian Stretch (current as of this bug date) and Debian Testing
as of this date.
STrace shows a large loop of checking what appears to be the application icon,
other than that I'd need guidance to produce necessary debug output.
