Hm...below are my results of running:

emacs -Q --font "-adobe-utopia-bold-i-normal--11-120-100-100-p-94-iso8859-1"

and

emacs -Q --font "-adobe-utopia-bold-i-normal--17-120-100-100-p-94-iso8859-1"

respectively. May be *-11-* is just too small to see glitches on my screen,
but I can't complain about ugly rendering.

IIUC yes, unless you install/remove new/existing fonts and
do 'xset +/-fp /path/to/new|old/fonts' as Emacs runs.

I'll try to check.

If you suspect the WM-side tricks, try to investigate this issue under twm
as well.
