Public bug reported:
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.
