Ligature bug

the problem i found, think, relates to the text rendering mechanic.

in Thai there are standard ligatures to make the top vowels into places. Normally Finding works fine, but, sometimes, also only some words, when I used direction keys to move the cursor passed all those text bound with ligature, those ligatures will become scattered some time like this12 (scattered one — compares with the correct one)

I’m not sure if you could find this problem within English ligatures. I wished this could be fixed so I don’t have to worry about the display.
