Red Hat Bugzilla – Bug 443008
Last modified: 2008-04-18 12:58:53 EDT
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):
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
Ugly ligatures makes text look misaligned
Characters that appear to share a baseline

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.
