I can also confirm this on a standard gnome-session, not Unity. It often happens that when I'm trying to run, for instance Gnome System Monitor, it indeed opens but I can't see the window. What I can notice is that cursor changes into ][ as I were hovering over a text. Right-click menu is also available - I can kill a process, for example. It is VERY annoying.
