Some glyphs being rendered at inconsistent sizes

Project Member Reported by reillyg@chromium.org, Aug 10 2016

Issue description

Version: 54.0.2824.0
OS: Ubuntu 14.04

What steps will reproduce the problem?
(1) Visit http://www.polygon.com/features/2016/8/9/12408750/no-mans-sky-first-impressions-review-preview-10-hours.
(2) Look closely at the glyphs in the article text.

What is the expected output?
The characters should all be rendered at a consistent size.

What do you see instead?
The x-height of some characters (looks like at least u, s, d and z) is higher than others.

See screenshot.

This issue is not reproducible on Chrome OS. I believe the font being rendered for this text is a WebFont.

Loading triager here, assigning to toyoshim@ for a first pass. I've also confirmed that it is broken on Linux but works on ChromeOS.

discussed with ksakamoto@.

This may be happening because of harfbuzz. As far as ksakamoto@ remember, Linux uses system library, and CrOS uses one in src/third_party/harfbuzz-ng.

Firefox running on Linux seems to have the same rendering issue.

eae@ can you investigate further?

CC: kojii@ who previously tried to use the same harfbuzz in both platforms.

If FF has the same rendering it's likely a fontconfig or harfbuzz issue. Behdad, have you seen this before?

Looks like autohinter fail.  Someone needs to grab the font, try to reproduce with ftview, and take it from there.  FreeType'ish issue; harfbuzz and fontconfig are irrelevant.

Unabel to reproduce with new-ish versions of freetype.
