Lower-case "s" too thin on Full hinting

Description of problem:

Bold lower-case letter "s" in serif looks in some cases too thin with Medium
and Full hinting, but look OK with hinting set to Slight or None. See attached
screenshots from LO Writer from F21.

See the "s" in a word "Midas" and "asked". It's 12 pt Liberation Serif, bold,
paper is enlarged to 157 % of width of A4 paper. When the zoom ratio gets
higher, the problem disappears, when zoomed out it's worse (but less visible).

Version-Release number of selected component (if applicable):

liberation-serif-fonts-1.07.4-4.fc21.noarch
freetype-2.5.3-13.fc21.x86_64
libreoffice-core-4.3.5.2-4.fc21.x86_64

How reproducible:

Always.
