Description of problem: See attached screenshot. DejaVu is the default font, and its western ligatures look, well, ugly, and are disconcerting. I can reproduce the problem with GTK programs but not QT ones. Version-Release number of selected component (if applicable): pango-1.18 How reproducible: Every time Steps to Reproduce: 1. Use DejaVu LGC or another font with ligatures 2. Type "confirms" (or "firefox") western text into Pango-using program 3. See apparent ugly baseline shift Actual results: Ugly ligatures makes text look misaligned Expected results: Characters that appear to share a baseline Additional info:

Created attachment 302839 [details] same word, MOZ_DISABLE_PANGO=1 Disabling Pango eliminates the problem.
IIRC, that problem happened when using the Freetype autohinter. Switching to the proper bytecode interpreter for font hinting solves that.
Then that's a freetype not pango bug IMHO. Please report it upstream.
yeah, it's autohinter issue with freetype.
