Problem
When launching thorium I get an incomplete GUI. If launched from the terminal I get the following errors:

#export DISPLAY=:0.0
#thorium
(thorium:10781): Gtk-WARNING **: 12:49:52.992: Theme parsing error: gtk.css:3536:25: 'font-feature-settings' is not a valid property name

Additional Notes
I've tried following the incorrect permissions prompt, but it doesn't help.
I'll try and grab a screenshot of the incomplete GUI.
