Troubleshooting
Non white on black fonts look terrible
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>
