Aliased Fonts in Xombrero

[Dutch Ingraham]

Hello all:

I'm having a problem with severe aliasing in Xombrero.  This only
happens on certain sites such as github and computerworld.  Most other
sites render fine.

I have followed the handbook at section 6.6. and here are the fonts I
have installed:

/usr/local/lib/X11/fonts % ls -l
total 200
drwxr-xr-x  2 root  wheel  66048 Nov 14 20:30 100dpi
drwxr-xr-x  2 root  wheel  66048 Nov 14 20:31 75dpi
drwxr-xr-x  2 root  wheel   1024 Jan 18 17:19 Liberation

drwxr-xr-x  2 root  wheel   1024 Nov 14 20:32 dejavu
drwxr-xr-x  3 root  wheel   1024 Nov 14 20:29 encodings
drwxr-xr-x  2 root  wheel  12800 Nov 14 20:31 misc
drwxr-xr-x  2 root  wheel   6144 Jan  7 19:03 terminus-font
drwxr-xr-x  2 root  wheel   3072 Jan 10 15:03 urwfonts
drwxr-xr-x  2 root  wheel    512 Nov 14 20:24 util
drwxr-xr-x  2 root  wheel   1024 Jan 10 15:02 webfonts

I also have each font in my font path in my xorg.conf.d/files.conf.
Further, I have a fonts.dir for most:

/usr/local/lib/X11/fonts/100dpi/fonts.dir
/usr/local/lib/X11/fonts/75dpi/fonts.dir
/usr/local/lib/X11/fonts/Liberation/fonts.dir
/usr/local/lib/X11/fonts/OTF/fonts.dir
/usr/local/lib/X11/fonts/TTF/fonts.dir
/usr/local/lib/X11/fonts/Type1/fonts.dir
/usr/local/lib/X11/fonts/cyrillic/fonts.dir
/usr/local/lib/X11/fonts/dejavu/fonts.dir
/usr/local/lib/X11/fonts/misc/fonts.dir
/usr/local/lib/X11/fonts/terminus-font/fonts.dir
/usr/local/lib/X11/fonts/urwfonts/fonts.dir
/usr/local/lib/X11/fonts/webfonts/fonts.dir

Others seem to have the same problem[1] but I haven't seem a solution
posted.

Any pointers to a solution are appreciated.  If you need further information,
please let me know.  Thanks.
