IFrame html controls problem

Hello,

I have a div element with an Iframe inside it ( its soundcloud.com embedded widget) and I am using a CSS3D renderer to render it as a CSS3D object.

The problem is that the controls in the iframe (play button, other buttons, etc) are totally displaced, at random ( to my eye) positions.

There is a working version at http://mdma.gr/three

( edit: in a mobile browser it works flawlessly)

Thanks in advance !

I think you run into the following bug (especially since your app works in Firefox):
