The display randomly gets corrupted with randomly moving block artifacts. This
means the display looks like a chess board with every other block being either
completely black or semi-transparent. In the latter case I can still see the
normal desktop but it appears like being looked at trough a 50%-gray filter.
The other blocks of the "chess board" are good. If the display content changes
(e.g. mouse movement), the "arrangement of the chess board" changes.

I can still work normally, start desktop applications, click around and shut
down the PC the normal way. But VT switching does not work anymore.

The crash seems to occur more frequently, if I play videos (mplayer or Flash),
but this is not a requirement.

The crash does not occur, if I use the blob firmware
(nouveau.config="NvGrUseFw=1").
