李定 - that's an interesting one; does it help matters if you go into Settings / Languages + Text and switch to one of the system STHeiTi fonts?
I tried all five fonts that are installed in my app (XinGothic SC, STHeiTi SC, STHeiTi TC, FZKaiTi, FZShuSong) but the issue still remains.
The problem seems to only happen on the first row of characters being displayed. See attached example of a nine-character dictionary entry where the first row gets cut off but the second and third rows wrap properly.
