Hello. This morning I updated to xf86-video-ati 6.7.196 after having used
xf86-video-ati 6.7.195 for a month without any problem.

In the few hours since the upgrade I had a strange problem: for two times while
I was normally using xorg the screen blinked, the status led of my monitor went
from green (normal) to yellow (changing mode) and then to green again while the
normal output was replaced by a grey pattern (picture taken with digital camera
attached in the next comments).

The mouse keeps working, the grey pattern reacted to changes (ie. activating
compiz effects with the keyboard shortcuts), switching to console and then back
to X fixed the problem in every occasion. The second time I actually checked
the refresh rate with the OSD menu: it changed from the normal "H 68.76 KHz V
85.22 Hz" to "H 67.22 KHz V 83.11 Hz". A screenshot taken with the PrintScreen
key showed the correct image.

I'm using an ATI Radeon X550 (RV370 PCI-E), more info in xorg.conf and
Xorg.0.log attached.
