[Bug 1722508] Re: Font hinting appears broken on 17.10 beta

[imachine]

Then see here the correctly displayed fonts on Gmail (also downloaded
from Gmail's server, no local font).

Works fine and hints correctly.

What gives?

Running last stable firefox (56.0, 57 all messed up, so locked 56 with
apt-lock)

Ubuntu 17.10

Bug description:
  It appears that font hinting in 17.10 (beta) doesn't work as expected.
  The issue is easy to miss if you have antialiasing enabled system-
  wise. However, if you install "gnome-tweak-tool" and disable
  antialiasing there, the problem becomes obvious.

  Here is how it looks on 17.10 beta:

  And here is how it looks on my 16.04 machine (and this is pretty much how it's supposed to look):

  * When comparing the pictures make sure you "Open image in new tab"
  and see them without browser zoom, otherwise the problem may no be
  obvious.

  I suspect that this issue is caused by a bug in some base font
  rendering package that Ubuntu uses (edit: the problem is probably
  caused by FreeType 2.8.0, see my comments below). A couple of months
  ago a similar issue was reported (and promptly fixed) in Chromium
  after they had changed something in FreeType rendering
  (https://bugs.chromium.org/p/chromium/issues/detail?id=748997).
