Peter: appears to be being rendered (in the panel) with BGR sub-pixel ordering (instead of RGB), and without the vertical autohinter in use.
For the sub-pixel ordering; there are some possibilities:
1. the system rendering settings aren't being read/used
2. the text is being rendered as white-on-black, and negated/inverted (in colour-space)
3. the text is being rendered right->left, and then the texture being mirrored (in horizontal space)
4. something else
For the latter:
1. the system rendering settings aren't being read/used
2. something else
