These are definitely due to hinting setup.  I personally prefer with
hinting, but I agree that this often deforms glyph forms too badly.

Try to put the following in ~/.fonts.conf:

================================================================
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "/etc/fonts/fonts.dtd">
<fontconfig>
  <match target="font">
    <test name="family">
      <string>IPAexGothic</string>
      <string>IPAexMincho</string>
      <string>IPAMincho</string>
      <string>IPAGothic</string>
      <string>IPAPMincho</string>
      <string>IPAPGothic</string>
    </test>
    <edit name="hinting">
      <bool>false</bool>
    </edit>
  </match>
</fontconfig>
================================================================

This will disable hinting for the specified fonts.
If this works better, we can put the rule into the package.


thanks,

Takashi
