Public bug reported:

The following behaviour appeared just after the upgrade to oneiric:

If I have two windows on desktop overlaying each other, when I click on
the background one the window comes to front then disappears for less
than a second and then reappears.

This doesn't happen if the two windows are separated. It happens 100% of
times.
