           Summary: ATI x1250 - Slow fullscreen video when compiz activated

Hello,

I have a HP 6715b laptop with an ATI x1250 video card. I also use an external
22" monitor connected to the VGA port of my laptop. I have set the screen
resolution to 1920x1080 in Gnome Display Settings.

The driver I use is the ATI one from the Ubuntu repositories.

When I play fullscreen videos with VLC, SMplayer or else, without having Compiz
running, it just works flawlessly, without seeming to freeze to calculate the
image.
But when Compiz is on, fullscreen videos get a lot slower. It is impossible to
watch a movie this way.

Another thing is that the desktop effects get really slow when it comes to
fullscreen windows: menus scroll down rather slowly, the windows "close
effects" is not smooth.

I have reinstalled Karmic Koala in its RC version and that problem isn't going
away...

My xorg.conf file is the original one, I have not tweaked it in any way...

Hope anyone else could reproduce this bug!
Thanks.

Chris
