429022 - [GTK2/pango] unavailable fonts or fonts without needed glyphs influence letter spacing

Status: RESOLVED INVALID

(Core :: Graphics, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

The three reftests:
layout/reftests/bugs/399696-standards-css.html
layout/reftests/bugs/399696-standards-html.html
layout/reftests/bugs/399696-quirks-css.html

fail for me on Linux because the letter spacing is different between the test and the reference.  This means that unavailable fonts or fonts that lack the needed glyphs are somehow influencing the letter spacing, which shouldn't be the case.

I probably need to debug further to figure out what's going on (particularly if others don't see this -- I'm not sure if they will).

[2008-04-14 18:29:18] <karlt> oh that's probably kerning when the fast path fails
[2008-04-14 18:29:46] <karlt> the tests would prolly pass with text-rendering:optimizeLegibility
[2008-04-14 18:29:55] <karlt> (if that's the only problem)

Closing GTK2 related bugs since we removed GTK2 support at the beginning of 2018 in bug 1278282. Probably best to open a new bug in the unlikely event that any of these are still relevant.
