Emulator boots to login but never displays UI

I follow the instructions on getting started with the emulator. When I run `ubuntu-emulator run myinstance` all I get is a black screen on the emulator that never changes. I do however get a log-in prompt and am able to interact with the emulator via command line. Below is the output from the boot sequence.
