It was reported with cairo that snapping of stems to integer widths for LCD rendering was no longer working:
https://bugs.freedesktop.org/show_bug.cgi?id=4302 Upon investigation this turned out to be a 2.1.9 / 2.1.10 change in FreeType. It looks like the problem is in af_latin_compute_stem_width(). As I read it variable vertical was supposed to be whether the stem being hinted is vertical, but was instead set to whether vertical hinting was enabled for the font. Here's a patch that works for me. Regards, Owen
