Monaco doesn't have an italic version, so Apple's ATSUI renderer (which 
TextMate uses) has to fake it.  When antialiasing is turned on, it uses 
the vector outlines, and looks somewhat passable.  When antialiasing is 
off, it tries to italicize the pixel font.  This shouldn't result in 
anything actually disappearing, but either way the output is going to be 
terrible.

I recommend either:

a) turn on antialiasing, or
b) turn off italics in your theme

Hopefully, TextMate 2.0 will allow turning on antialiasing only for 
bold/italics, but leaving it off for plain text.  That would be awesome. 
  Until then, italic unantialiased Monaco is just going to look horrible 
and there's nothing to do about it.
