I experienced the same yesterday. It's a combination of:
  1. Stale ~/.Xauthority file
  2. Removing ubuntu-desktop-mir doesn't seem to remove the config and it keeps using USC.

Solution:
  1. rm ~/.Xauthority
  2. sudo apt-get remove unity-system-compositor

The first issue is an old X bug. The second I think is a packaging bug of ubuntu-desktop-mir.
