characters should obviously have the same width, and when they don't, it
can be a problem with the font definition (the font designer wasn't careful
about keeping monospacing), or there are missing characters that get
substituted from a similar font, or the entire font is substituted. I
expect it is the latter, because I am cursed with the ability to notice
miniscule deviations in alignment/spacing and it's been a long time since
I've seen any issues with FreeMono or Droid Sans Mono captions. Hopefully
Mike's suggestions can root out the root cause.

not sure if it's a Qt bug or what not. what's for sure with a theme
like MythAeon, fonts are rendered very differently and theres not
enough space to display the menu entries' so you see them scrolling
continuously...
