--- Comment #27 from Alexei Podtelezhnikov apodtele@gmail.com --- Here is what happens. At 96 dpi, 8 points corresponds to 10.6666 ppem. This used to be rounded up to 11 as if you requested 8.25 points. Now the rounding is not happening and FreeType respectfully hints and delivers results that correspond to 8 points better. Since hinting is discrete this may dramatically shrink each letter by 1 pixel, which adds up in monospace terminal window.
Freetype does not do anything wrong, does it?
