Public bug reported:

This is mostly a tracking bug for this discussion on ubuntu-devel:

https://lists.ubuntu.com/archives/ubuntu-devel/2016-February/039224.html

The following precise-era patch was recently removed from freetype:

http://bazaar.launchpad.net/~ubuntu-
branches/ubuntu/wily/freetype/wily/view/head:/debian/patches-
freetype/revert_scalable_fonts_metric.patch

which caused a number of visual effects in various applications.  In
Emacs, the lines get vertically closer so that more lines are visible on
screen.  This is subtle and doesn't look too bad otherwise.

However, in Claws-Mail several negative effects were noticed.  The lines
in the Summary window are more squished together and the characters
appear squished too.  This is with Sans 10 font.  This is less readable.

In the Message window it's worse.  There I use Ubuntu  Mono 14.  The
problem isn't the vertical spacing, but the horizontal spacing.  Now
there is more space between characters and that actually makes the
window less readable.

I will contact the upstream Claws mailing list to see if they have any
thoughts.
