You're right. I tried without DRI and got the same after 6
days. Then, I went back to 6.7.196, but the same happened
today, after 3 days. So, it isn't the ATI driver.

The strange thing is that it always happens while I move the 
mouse. And in the four until now, while the system was idle and 
I moved the mouse inside a window running screen.
