Troubleshooting

Non white on black fonts look terrible

Example of terrible looking fonts

If your non white fonts look terrible in GIMP, you might try to turn off sub-pixel hinting for GIMP. You can do this by creating a fonts.conf in the GIMP user configuration directory (e.g. $HOME/.gimp-2.8/).

FILE $HOME/.gimp-2.8/fonts.confTurns off sub-pixel hinting for GIMP

<fontconfig>
  <match target="font">
    <edit name="rgba" mode="assign">
      <const>none</const>
    </edit>
  </match>
</fontconfig>
