I just installed Spacemacs using https://github.com/railwaycat/homebrew-emacsmacport When I open it on my Retina Macbook Pro I see a "border" on the powerline and the color isn't even (notice under utf-8 on the right that it's thicker).
How do I remove either the darker/thicker border or remove the powerline border?
I was unable to find this is the readme for powerline for emacs.
