Bug#441902: xserver-xorg-video-ati: 6.7.192-1~7.2 crashes xserver with xv video playback on compiz

Hi Michael,

> I'm following up to the bug report, please do so as well.

I'm not sure what this means, but I'm guessing that I didn't cc the
debian bug report system? I have done so this time.

Turns out it complained with 8Mb but is fine with 16Mb.

I have re-enabled page flipping and it seems to be better. There is
still a distortion of my screen when swithcing to/from the virtual
consoles, but this generally goes away after a couple of seconds. If
not, a restart of compiz will refresh the screen. I can file a separate
report regarding this (it has been around for a long time.)

Xorg no longer crashes when entering or leaving X, however the EXA
performance is still much poorer than XAA. To be sure, it's better than
it was but there is still a great deal of stuttering when switching cube
faces and even xterm windows do not draw cleanly, resulting in
strange refresh effects. Note that I tried this with the ati driver in
unstable and then in experimental, without much difference between the
two.

Also, I still get these, should I report this as a separate bug?
