Public bug reported:
This problem occures on all programs, which has a scroll button, such as
Firefox, Google Chrome, Terminal a.s.o. It appears time by time,
normally 5 minutes after starting the computer and mostly during using
the scroll button. The bottom half of the program window is getting
black and the system is freezing. Sometimes it occures also while doing
nothing. In that case the computer is only freezing without black areas
on the display. I use a Nvidia Geforce 8400 M.
