Since fontconfig-2.11 the xml:space attribute makes it reject /etc/fonts/fonts.conf, so it renders garbage and eats lots of CPU. To use anything linked to fontconfig-2.11 you need to have this patch applied to your running NixOS. That's why I'm pushing it to master before the fontconfig update (as soon as I found and tested the fix).
