Subject: /usr/bin/plasmashell: 100% CPU usage when network monitor widget is added
Date: Wed, 02 Sep 2015 22:31:01 -0700
Package: plasma-workspace
Version: 4:5.3.2-4
Severity: normal
File: /usr/bin/plasmashell

Dear Maintainer,

When I add the "Network Monitor" widget, plasmashell uses 100% CPU.
(Actually a bit more, but the rest occurs even without that widget).

This did not happen in KDE 4.

Thank you for your report.

This looks like an upstream bug.

You can help by searching on bugs.kde.org for an issue like this and if there 
is none reported, report it there and post a link to this bug report.

Thank you,
Martin

I couldn't reproduce this issue neither in testing (4:5.3.2-4+b1) nor in
unstable (4:5.4.1-1), can you still reproduce the problem? If so is the applet
responsive?

Happy hacking,

I also experience this bug. However I noticed that after some time I
will have several plasmashell running, one of them taking 100% of the
CPU it's running on. It thus seems this bug triggers in return #797862.
