When I say it resolves itself, it never does so spontaneously. It sometimes resolves after a complete PC reboot, and once or twice when I tried unity --reset and unity crashed spectacularly.
Also if I disable the unity plugin, it resolves itself immediately, so like Daniel suspects in bug #861061 it may well be that unity is at fault rather than compiz.
