Bizarre X windows behaviour?

[Zachary Uram <netrek@gmail.com>]

Running Debian lenny. I installed the Catalyst driver (from
manufacturer) for my ATI Radeon
HD 4550 card and it seems to be working, but I noticed something weird.
Now when I move a window it no longer shows the window static as it is
being moved,
it's like it keeps redrawing it as I move it. So as I drag it it will move it a
little then redraw the window, move it a little, then redraw the
window, etc. Also I noticed in Firefox when I scroll it does the same
thing, instead of keeping the text fixed it redraws the text as the
scroller moves. i really don't like this. It didn't do this in Ubuntu
and I used to same driver. How can I fix this? Here is my /etc/X11/xorg.conf

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*

# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg
