Line Renderer does not work in Web Player

I can not get the Line Renderer to display anything in the web player. Works fine in the editor and when I build to PC. Any reason for this? Answers or suggestions to debug issue this would be appreciated.

Turns out it seems to be some sort of browser compatibility issue. Didn't work in google chrome, worked fine in Internet Explorer and Firefox. However did work in chrome for a friend. So just generally very odd.
