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 stack.
