Ian,

Your screenshot shows that Compiz is getting bad textures from the driver/hardware. Compiz always renders everything in triangles but their textures should fit together seamlessly. Most likely it's a driver bug.

You might want to try installing AMD's own driver "fglrx".

Alternatively, you might have luck with a workaround like:
    sudo apt-get install compizconfig-settings-manager
    ccsm &

The CCSM workaround has not resolved the problem. Unfortunately, whenever I install fglrx, lightdm appears to crash and I wind up with a black screen with a white cursor in the upper left corner of the screen.

I was able to install the fglrx driver today and I am no longer affected by the bug.

This problem should be solved in the upstream 3.13-rc6 kernel by this patch:

Ian Nicholson, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
