I've experienced this -- excuse me, as I don't know the window management vocabulary, here. The window that appears is the 'guide window' that you see when you when you snap a window to the left of the screen, and unity shows you that it will be maximized on the left half of the screen.
It's my impression that I have seen this bug only in sessions where I have previously snapped a window to the left or right. If I haven't done so, since I logged in, I don't see this spurious 'guide window'. I can't be sure if that's 100% accurate. Thanks.
