The same did happen with 2.1.8 (which defaults to autohint) we had the
same issue, setting the FT_LOAD_TARGET_MONO flag to Load_Glyph made it
work.  Upgrading to 2.1.10 showed the same issue, due to the switch to
autofit.

I don't believe that any AA is applied to X fonts, unless an extension is
in use.  So by default they're 1bpp images, so setting MONO makes sense. 
Certainly the glyph render is done using MONO, eg:
FT_Render_Glyph(face->face->glyph, FT_RENDER_MODE_MONO);

We're using the X.org 6.8.2 font library, so I'd expect it's fairly
uptodate and relatively bug free but I should probably feedback to them
that it should be using the FL_LOAD_TARGET_MONO for the load_flags to
Load_Glpyh, since we're extracting 1bpp images.

Thanks,
Chris
