Apologies for the incomplete message (mis-clicked submit while adding
attachment).

I am using OpenSUSE 11.3, with KDE version 4.4.4. By default, the system is
using nouveau driver version 0.0.15 20100401 (this is taken from the YaST
repository). The video card is Quadro NVS 295. I am also attaching my XOrg.log
for additional version information. If any more information is needed, please
let me know.

Basically, the taskbar is the only part of the screen that I've noticed so
far
as being corrupted (is KDE using some transparency effect there?). If I replace
the driver with the proprietary one, the taskbar shows up correctly (light
gray, icons are no longer corrupted).

One more observation:

The analogue clock is also corrupted from time to time (see snapshot). Again, a
transparent widget...

Thanks Marcin!

Yes, it could be a KDE problem (it defintely looks like the one described on
their forum). It is probably something more subtle related to the interaction
of KDE with the drivers, since:

1) It goes away if I install the proprietary NVidia drivers
2) It never occurs on my laptop with Intel graphic card

I'm going to try KDE 4.5 and report back on this.

Many thanks,
Stefan,

Yep, I installed KDE 4.5 and it went away. So indeed, it seems to be a KDE bug
that only surfaces in conjunction with the nouveau drivers.

I've closed the bug report. Thanks Marcin for the useful feedback!

All the best,
Stefan.
