Public bug reported:
When the screen is locked, plasmashell 100% a CPU core because of a
misbehaving IM icon in the system tray.
By default, "set my status to away when the screen saver is activated"
is enabled in IM settings, and the IM icon is also shown on the plasma
panel. When the screen is locked, the IM status is set to away and the
icon changes (at this point I can't see what's happening behind the lock
screen). ssh'ing in, I can see that kwin/plasmashell/xorg are pegging a
single core, probably because the icon is rapidly updating or something.
Workaround:
1. Disabling "set my status to away when the screen saver is activated"
prevents the issue from happening
2. Hiding the IM icon from the system tray also works.
Affected packages:
plasma-workspace 4:5.2.1-0ubuntu3
kde-telepathy 0.9.0ubuntu1
** Affects: plasma-workspace (Ubuntu)
