Comment 1 Thomas Lübking 2011-11-13 12:46:03 UTC
driver bug
disable blurring, down- or upgrade mesa, or force direct rendering


depending on your GPU/driver this might fail elsewhere (esp. w/ fglrx - use the
radeon driver in case and if you can)

Comment 2 Martin Flöser 2011-11-13 15:15:40 UTC
Just for the record: the checkbox "direct rendering" has been removed in 4.8 
exactly because it is a "break my system" checkbox.

Direct rendering does not work reliable with fglrx and is terribly slow.

You can find some driver recommendations in my "how to improve desktop effects 
performance" tutorial on userbase I wrote yesterday:

Ok, but
