Kde4 panel process popups cause very high plasma+Xorg cpu load
Last modified: 2008-04-15 08:46:22 EDT
Description of problem:
Load the KDE4 desktop and start a process so that the screen bottom
kde panel shows a process entry. Hover the mouse over the
panel so plasma shows the process details under the mouse-->
Xorg and plasma cpu load goes to 100% (total cpu% of the two)
for as long as the mouse triggers the panel popup for the process.
Version-Release number of selected component (if applicable):
Fedora 9 Beta
Steps to Reproduce:
1.Load the KDE4 desktop
2. start a process so that the screen bottom kde panel shows a process entry.
3. popup display causes plasma and Xorg cpu usage to go very high
xorg/plasma cpu usage goes very high for as long as mouse forces
a panel popup.
plasma should not be designed so that a static popup causes abnormally
high cpu usage.
And why is this Xorg and not KDE bug?
