Also, the background repainting bug is still there in KDE, but not in Gnome, i.e. it's likely to be a KDE issue.
Yes, that one is a known KDE issue. It might still ultimately be the video driver(s)'(s) fault, or maybe X11's, but only KDE is known to trigger it. It might also be a bug in KDE itself.
