Comment 1 Thomas Lübking 2012-01-02 14:59:47 UTC 
You're probably using fglrx?
(Disable blur and set the scale method to "smooth" in this case, "kcmshell4 kwincompositing", 3rd tab)

*** This bug has been marked as a duplicate of bug 270818 ***
Comment 2 Diego Ercolani 2012-01-02 15:06:22 UTC 
I confirm you that I'm using fglrx. I was using the "rapid" method now I set "smooth"
Thank you

thi is the output of kcmshell4 kwincompositing

Comment 3 Thomas Lübking 2012-01-02 15:12:10 UTC 
crash occured in the blur effect, which must be disabled.
smooth & fast should both be fine, where smooth will likely look better - only lanczos will break on that driver replacement ;-)
