Hi Alex,

I'm currently not using any other DE than KDE. However, I can install GNOME or
something similar, for testing purposes, if you think that helps nailing this
bug down.

Today, I compiled the new beta2 of KDE 4.8.0. This version shows the same
artifacts as KDE 4.7.3, which I used before. Even if I create a new user, the
same issues appear again.

If I switch to fglrx, everything is working as expected. Screenshots work, and
no glitches appear. And there are no more crashes. So, it's not a
hardware/temperature issue, but definitely related to the KMS-based graphics
