I have similar problems. Window Manager keeps crashing intermittently dropping me out to the KDE login screen. Occurs most frequently when scrolling in Firefox.
Intel Corporation 82852/855GM Integrated Graphics Device in a laptop. Was completley stable running every version of Kubuntu that was installed on it (Feisty, Gutsy, Hardy). Now crashes frequently with Intrepid. Im also experiencing the visual glitch that happens when an app goes full screen. http://forum.kde.org/showthread.php?tid=6511 What are you all seeing in /var/log/kdm.log?
