This happens to me on 13.04, at random, when trying to focus a new window. Randomly clicking other windows will eventually solve the problem, but usually makes a few others black and/or transparent first, so it usually takes a number of clicks to eliminate the symptoms completely. I have also noticed that some windows appear without the top button bar of the window for a while in conjunction with this problem.
