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 1400x900 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
