Public bug reported:

Binary package hint: compiz

Occasionally when I press ALT+TAB I see one of the window thumbnails
being shown twice. That is, if I have two windows open, I will see tree
thumbnails instead of two, one of them being a duplicate. When this
happens, it coincides with the view being different; normally the
thumbnails are simply shown side-by side, but when I get the error I
will see a view where the off-center thumbnails are shown with a three-
dimensional effect (it's difficult to describe, but I suppose it's one
of the alternative views I could choose if I changed my options).

This looks to be a mere presentation glitch, as task switching works
fine. However, it is confusing.

I can reproduce this about once per login session. I have not found any
usage pattern to reproduce it.
