That's caused by fontconfig. You might want to create a ~/.fonts.conf
with this:
<?xml version="1.0"?><!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match target="font" >
<edit mode="assign" name="rgba" >
<const>none</const>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="lcdfilter" >
<const>lcdnone</const>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="hintstyle" >
<const>hintfull</const>
</edit>
</match>
</fontconfig>
lcdfilter does affect subpixel (color) hinting (i think), while hintstyle
seems to affect the "crispness".
http://fontconfig.org/fontconfig-user.html for possible values.
