Very slow 2D with radeon xpress 200 and composite

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
    Identifier   "Monitor0"
    VendorName   "AUO"
    ModelName    "8174"
EndSection

Section "Device"
    Option "AccelMethod" "EXA" # I tried with XAA too
    Identifier  "Card0"
    Driver      "radeon"
    VendorName  "ATI Technologies Inc"
    BoardName   "RC410 [Radeon Xpress 200M]"
    BusID       "PCI:1:5:0"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device     "Card0"
    Monitor    "Monitor0"
    SubSection "Display"
        Viewport   0 0
        Depth     24
    EndSubSection
EndSection

Section "DRI"
    Mode 0666
EndSection

My note specs:
Celeron M530
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.

Re: Very slow 2D with radeon xpress 200 and composite

you might try to check what configuration the livecd uses:

* version of xorg
*version of the driver (which driver?)
* xorg.conf
