Public bug reported:
The virtual desktop picker provided by Compiz/Unity does not clean up
animation-artifacts when used on a stacked monitor configuration with
mismatched display sizes (laptop panel below, large secondary external
LCD panel above).
I've attached a screenshot demonstrating the issue. It looks like the
blank areas of the screen aren't being cleared on the top monitor.
Also, while mirror images of the picker are shown on both the top and
bottom monitor, only the bottom picker is interactive. I can click on
the top part, but the it has no effect.
A quick fix might be to prevent the picker from writing any output to
the top display? I defer to someone who knows the codebase on that one,
but the bottom display (the primary LCD) does seem to be behaving more-
or-less as it should.
