It's interesting that the system still remains vaguely usable: when I maximise a window, for example, it will redraw well (no artifacts at least in the contents; the KWin parts will remain garbled) but this doesn't really last. Anyone seeing this as well, and is there anything I can do to help debug it? best, Jaap -- "Then I'll tell the truth. We're allowed to do that in emergencies."
