Perhaps you should ask on an Ubuntu mailing list, as you
describe an Ubuntu issue, the assumption that Freetype is
involved is not entirely plausible.

Perhaps you should also ask whoever setup the font configuration
in that VM.

That is confusing: If the way to reproduce is to choose a
'fixed' font, why mention Liberation here?

XLFD is a font selection syntax, while PCF and TTF are font
formats. If Ubuntu were using PCF fonts (and 'fixed' usually is
a PCF font) to satisfy requests in XLFD syntax, since they are
not outline but bitmap based they look bad when scaled by the
X11 font system.
