As discussed in thread

http://lists.nongnu.org/archive/html/freetype/2014-07/msg00002.html

there are severe rendering problems with subpixel hinting.

Attached are the results of

ftview -e unic -f 25454 14 msyh.ttf

using the current git version, with ftview's `H' key to switch between v35 and v38 rendering. As can be seen, in ClearType mode the first glyph gets heavily distorted.

For reference, I'm also attaching a VTT rendering image of the problematic glyph as sent by the OP to the mailing list.
