As some additional information, there appears to be a per-user component to this. The steps I followed above only fixed my user account; my guest account was still broken. I had to remove it again, log in as my guest user, log back in as myself, then reinstall to fix both. It's acting like some user configuration file has to get built while compiz is not installed in order for the panels to function properly, though I don't know if that's actually the case.
