Sandboxed apps look ugly, why?

Created by Sergey "Shnatsel" Davidoff on on 2011-07-21

Sandboxed applications try to use the theme set for the host system. If the sandbox doesn't contain the theme host system uses, it will fall back to the ugly default theme.

To prevent it, set your host's theme to a one that's present in the sandbox you use (Ambiance or Radiance for Ubuntu, elementary for elementary OS), or install your host's theme in the sandbox.
