now with LO4.0 the error happens even when KDE-integration is not installed.

can't see any scrolling problem on Fedora 18.

does your problem look something like this screenshot:

which is from bug 60537.

can somebody check this on openSuSE?

that definitely looks like a duplicate.

please provide some info on the graphics driver you use.
especially whether you use the Nouveau driver.

you can find out by looking at /var/log/Xorg.0.log

hwinfo from openSUSE-12.2 system where the problem did not happen

Hmm, I am not able to reproduce this. I tried it on openSUSE-12.2, x86_64, KDE4, with both upstream and SUSE-specific builds.

To be honest, I saw some artifacts when the screen was being repainted but I newer seen any artifact when I stopped scrolling and repainting finished.

It seems that I use the potentially problematic Nouveau driver. See the attached hwinfo for more details.

I guess that the problem happens only with a specific combination of the graphics card and driver.
