Hi guys, I'm having some trouble here. When I enable composite, either in GNOME or KDE, scrolling/resizing windows becomes too slow. If I disable composite, everything comes back to normal. I tried with xf86-video-ati and catalyst, and nothing changes. 3D performance is OK. I ran a Kubuntu LiveCD, and even with KDE's compositing enabled, scrolling/resizing windows is perfect, so I believe there's some problem with my Xorg's configuration.
Here my xorg.conf:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
EndSection
Section "Files"
ModulePath "/usr/lib/xorg/modules"
FontPath "/usr/share/fonts/misc"
FontPath "/usr/share/fonts/100dpi:unscaled"
FontPath "/usr/share/fonts/75dpi:unscaled"
FontPath "/usr/share/fonts/TTF"
FontPath "/usr/share/fonts/Type1"
EndSection
Section "Module"
Load "xtrap"
Load "dbe"
Load "glx"
Load "dri"
Load "extmod"
Load "freetype"
EndSection
Section "Monitor"
#DisplaySize 330 210 # mm

My note specs:

2 GB RAM
Radeon Xpress 200M
Thanks in advance.

I think I've solved the same problem with option:
Option "DefaultDepth" "16"
I've ati X1100/X200M.

you might try to check what configuration the livecd uses:
* version of xorg
*version of the driver (which driver?)
* xorg.conf
