I have just upgraded my Ubuntu 12.04 to 12.10 and there is following problem.
When I press super button to show Unity Dash I get wrong background image behind the dash box. Especially I can see part of the bottom of the screen. Also when I set transparency to top panel the background behind is not correct.
Here is an example with Mc Duck picture:

My system preferences:
Ubuntu 12.10 32-bit
Intel® Pentium(R) CPU G840 @ 2.80GHz × 2
GeForce GTS 450/PCIe/SSE2
Any help will be highly appreciated!
