> Do you use hintfull in your fontconfig hintstyle settings?

No. I have a powerline config in my fontconfig conf directory though, which contains

```xml
 <match target="font">
  <edit name="hinting" mode="assign">
   <bool>false</bool>
  </edit>
 </match>
 <match target="font">
  <edit name="hintstyle" mode="assign">
   <const>hintnone</const>
  </edit>
 </match>
 <match target="font">
  <edit name="rgba" mode="assign">
   <const>bgr</const>
  </edit>
 </match>
 <match target="font">
  <edit name="antialias" mode="assign">
   <bool>true</bool>
  </edit>
 </match>
```
I'm attaching the full file just in case, and I'm going to test stuff with it.
