OS:                Linux

hi guys,

If i turn the desktop effects off, I sometimes get visual artifacts. 
For example instead of showing the taskbar, the below window background image is shown. It seems like the taskbar button is not drawn over the background image. I will attach a screen shot which show the issue. I don't have this kind of problem if desktop effects are turned on.

raffaele@raffaele-desktop:~$ kde4-config --version
Qt: 4.7.0
KDE Development Platform: 4.6.00 (4.6.0)
kde4-config: 1.0
raffaele@raffaele-desktop:~$ uname -a
Linux raffaele-desktop 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:48 UTC 2011 i686 GNU/Linux

I'm on kubuntu 10.10

Reproducible: Sometimes

kwin isn't responsible for non composited painting.
re-assigning to plasma, but it's likely bug #177959

This was actually an X.org bug fixed upstream.
