I don't see how Pango could be relevant: AFAIK we don't use any of it
in Emacs.
It could be a Cairo issue, in which case it is somewhere in the bowels
of Cairo, not in Emacs code proper.

If this is the same issue, how come you sometimes see correctly laid
out text and sometimes incorrectly laid out text? Emacs doesn't
change anything in both situation, and I'm not aware of any handling
of "hinting" on our side.
