You should not #define TT_CONFIG_OPTION_UNPATENTED_HINTING
That's because, if you do so:

- FreeType will use the auto-hinter by default

- unless you open the font with very special arguments,
  in which case, it will use a modified bytecode interpreter
  that, among other things, doesn't interpret delta hints
  at all.

this #define is only used to be able to support certain
Asian fonts which heavily rely on TrueType bytecodes to properly
build composite glyph images, but who fortunately do not use
any of the patented bytecode operators.

For all other fonts, it will render huge anormalities

Hope this helps,
