Bug Description
After working for a while with frequent window-switching, windows start to display invisible in the spread. Clicking by guessing the invisible windows' positions reveals them again and they are again visible afterwards.
This happens to all sorts of programs that have a few windows open (e.g. Chromium, Nautilus, Gimp...). I can't reproduce this behaviour at will but it is certain to pop up after a while of working with unity.
I have attached a video showing the described problem.

This doesn't seem to get better with recent updates. As of now, not far from release, ubuntu is not really usable with this bug for anyone doing non-trivial work. (at least on this hardware configuration)
