UpFront not loading correctly?

I am having some trouble with UpFront while working on a new website. Any time I attempt to edit a page, the element controls do not appear, and some of the resources load incorrectly. See the screenshots below for an example.

The site I'm working on is being served from an IP address while the domain propagates. Is this causing the issue? If not, how can I resolve this?

The only plugins installed is WPMU Dev Dashboard. I have updated and reinstalled the theme/UpFront, reinstalled WP Core, tried in other browsers, and cleared all caches.
