When I run it, I first see a webpage loading then it suddenly disappears and the whole page becomes white. There is no UI, but when I hover over the white nothing, it appears as if the webpage is still underneath as the cursor behaves as it would if there were text and hyperlinks. I am on Ubuntu 14.04, by the way. Screenshot: http://i.imgur.com/ixQj4sI.png http://i.imgur.com/ixQj4sI.png
