Bug Description

When I launch the Workspace Switcher with a second monitor attached to my laptop, set to a same resolution as the laptop display, the rendering is incorrect. The workspaces of the first display overlap onto the second display.
See attached screenshot - the red rectangle has been added to show the extents of the first display.

Setup:
Laptop: Acer Aspire Timeline X 4830T: Intel Graphics 3000
Second Display: VGA monitor

Workspace same resolution bugs Edit (1.1 MiB, video/mp4)

I can confirm, I have a multimonitor setup and unity from trunk (rev. 2117).
It also does not respect Multiple Monitors UX Specification, because the four workspaces are splitted 2 on primary display and 2 on secondary.
I attached a video that underlines the problem (the blueish was added by avidemux during recompression!).
