ugly fonts

For the last several weeks, most of the fonts in Rawhide have looked
pretty ugly.  Spacing between letters is weird, letters are "chunky" and
not smooth looking, etc.  I am just wondering -- is this something that
is likely to be peculiar to my setup, or is there something going on
with the font-related parts of the distro that are responsible?  Are
there any sorts of things I can try to make it look better?
