@jordyd I think whatever font you're using there doesn't play well with Powerline's glyphs. Look for fonts patched specifically for Powerline.
@jordyd https://github.com/powerline/fonts -- these should do
@arisunz I love fonts and will install all of these immediately
@arisunz Oh! I have to *patch* the font...
@arisunz Well, use the patched versions anyway
@arisunz Thank you. The spacemacs installation instructions mentioned Source Code Pro, which I installed, but it doesn't appear to be using it. Maybe there's a font cache or something that needs to be updated
