I had a similar bug earlier, where the dash would also appear below the other windows. But I couldn't reproduce it on my laptop, now I can. So, all the windows created by unity (switcher, dash, dash popups) appear below other windows, _but_ input still goes to them, so it's only the visual part that is stacked incorrectly.
