Bug ID: 448032
Summary: Volume monitoring feature causes excessive and
constant CPU usage when applet is placed on the
desktop
Product: plasma-pa
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: applet
Assignee: now...@gmail.com
Reporter: n...@kde.org
CC: plasma-b...@kde.org
Target Milestone: ---
STEPS TO REPRODUCE
1. Put a plasma-pa applet on the desktop
2. Start playing some music
OBSERVED RESULT
Plasmashell idles at 100% CPU usage, even when the applet is not visible
because it is covered up by other windows
EXPECTED RESULT
the applet should not consume 100% CPU usage when on the desktop. At the
minimum, we shouldn't do pointless work to monitor the volume while the applet
isn't even visible because it's covered up by windows.
ADDITIONAL INFORMATION
The CPU usage is not as high for me when the applet lives in the System Tray
and its popup is open; when doing this, plasmashell idles at about 40% CPU
usage, rather than 100% when the applet is on the desktop. And when the popup
is closed, CPU usage goes down to practically 0% as expected.
