Zoom factor breaks minimap

[veeeeeeeeeee]

Minmap breaks when this snippet is included in init.coffee. It becomes blank and unscrollable.
require('electron').webFrame.setZoomFactor(0.9)

I've had this settings since I first installed atom and fiddling around with the styles. Not entirely sure how atom renders its UI webframe but what I'm using might be some sort of legacy function.
