[Bug 419054] [NEW] kdeinit4: plasma-desktop takes 60-90% of CPU

[moky]

Public bug reported:

The process plasma-desktop uses most of time between 60 and 90% of my
CPU when KDE is started.

In order to fix the situation (and make plasma-desktop use ~ 10% of CPU), the following works most of time
1. right click on the desktop
2. unblock widgets
3. re-block widgets

When it does not work, the fact to change the wallpaper fixes the
situation (I'm using globe -> OpenStreetMap). Notice that re-changing
the wallpaper to OpenStreetMap does not re-create the problem.

$ lspci |grep VGA
2:00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

I have the same problem with an Nvidia card on an other computer.
