Actually, for the OSD fonts (and only OSD fonts), Myth is using 
freetype2 directly.  See libs/libmythtv/ttfont.{h,cpp} .  Oh, it (and, 
especially, the OSD code) is a bit of a mess.

Note, also, that the (eventual) plan is to change the OSD to use 
mythui.  When that's done, it's quite likely that the bug will be thrown 
out with the rest of the current OSD code.  Therefore, if you can get 
the workaround to work sufficiently well, ...

If you're interested in working on the mythui conversion, Daniel K. and 
Stuart Morgan would probably be the best sources of information about 
the OSD and mythui, respectively.
