Reboot wasn't necessary. I was able to launch USC from the applications menu and then close it again, and it appears to have cleaned up after itself this time (at least I haven't seen the phantom image since then, and during the time which has elapsed I would have seen it multiple times, so I've got my fingers crossed).
