Mouse offset in canvas [fabric.js]
===

I've read 3-5 topics about mouse offset, but i still can't get where is the mess.

In my case everything works fine in 60%. In other 40% mouse is offset. [Demo here][1]
(IE & Chrome have the bigest mess)

I've tried to edit stylesheets and parent div but nothing. The worst thing: i don't see any regularity. I will be greatful for any help.
