Default Dragging a window on Ubuntu Linux desktop results in screen tearing

I have installed Ubuntu Linux and the latest proprietary graphics drivers on my laptop and when I drag a window around the screen or watch a video with lots of movement I see screen tearing.

The same problem persists even if I enable "Sync to VBlank" in the NVIDIA X Server settings.

My system specs.

GPU: NVIDIA GeForce 9400M G
GPU drivers: NVIDIA version 195.36.24 (from Ubuntu's proprietary hardware drivers)
display: 1366 x 768 @ 60 Hz laptop LCD display (there is also a HDMI connection but I'm not using it)
computer: Acer 5737Z laptop
OS: Ubuntu 10.04 LTS, 64-bit
Kernel: Linux 2.6.32-22-generic
GNOME 2.30.0

Below is a screenshot of the Firefox window tearing while being dragged from left to right.
