Re: [ft-devel] Render a text on Horizontal using a ttf file which contains also Vertical metrics (Re: Freetype-devel Digest, Vol 148, Issue 25)

I doubt that's the case - at such low resolution, I'd suspect that it is 
because of rounding issues somewhere.

fuller code and actually say what font you are using would be useful.

BTW, the freetype dlls you get from SharpFont is extremely old - you can query 
what version of freetype it is by doing something like this:

using SharpFont;
...
_lib = new Library();
Console.WriteLine("FreeType version: " + _lib.Version);
...

I believe they were a late 2.5 or at most early 2.6. You can get 2.7.1 from 
download the whole of bin/Win32 or bin/Win64 (depending on which one you want) 
from
 https://github.com/HinTak/Font-Validator/
and see if that improves.
