I'm using Ubuntu 13.10 and once I noticed behaviour described in comment #4: alt-tab works, but it's window is behind other windows --- I can see it if I do alt-tab on workspace without windows. Also, such bug once occured on computer of my friend.
HUD dialogs (raised by pressing "alt" or "super" key) in background too.
