It might be related to "kephal" in KDE 4.2, but I didn't find much information about that. Basically the KDE developers are now arguing that it might be a <A HREF="http://bugs.kde.org/show_bug.cgi?id=170920#c22" REL="nofollow">video driver issue.</A><BR/><BR/>If people here are all using the intel driver that might well be the problem, at least for 4.2.x.
