Found same problem in 2.5.3

In version 2.5.2, with FT_LOAD_TARGET_LIGHT flag, some Hangul glyphs in NanumGothic font are rendered incorrectly and in unreadable way. Some strokes in small characters disappear with this flag. It was fine in 2.4.12.

Screenshots from Ubuntu issues:

With 2.5.2: https://launchpadlibrarian.net/172899667/1404_font.jpg
With earlier version: https://launchpadlibrarian.net/172899684/1204_font.jpg

See imcomplete circle in "옵"(U+C635) character.

This problem breaks Ubuntu 14.04 Korean default desktop with other change; 14.04 changed hintstyle default to "slight" and cairo doesn't respect font specific fontconfig settings.
