Compositing: I guess so, if I go to System Settings -> Desktop effects
are ON. I shut it off and the problems seems to have gone, BUT:
1. the first time I tried to re-open the desktop effects settings, KDE
threw me out of the desktop, back to KDM.
2. now everything is greyed out with an information message "Desktop
effects are not available on this system due to the following technical
issues:" (but no issue description).
This looks like a graphics or bad hardware issues. Do you have
composting enabled? Also what's your graphic chip?

So, something between drivers and KDE indeed. Any further idea?
