According to the experiments so far, it seems to be caused by Xft in
addition to some conditions that are not yet sure (maybe library
versions or settings?).

Emacs 22 uses the traditional text drawing aka X core fonts, and many
GNOME and GTK+ applications use cairo rather than Xft.  A workaround
would be to use the traditional text drawing as in Emacs 22 by
preferring the X core font driver to the Xft one (see `fontBackend' in
the "Table of X Resources for Emacs" node in the Emacs info).
