    <thetext>Example URL:
http://jsfiddle.net/yjydm7ce/1/

Steps to reproduce the problem:
1. Any content with transform: scale
2. Use Browser Zoom that is not 100%
 

What is the expected behavior?
All content shall scale, using browser zoom, in unison.

What went wrong?
Transformed content scales differently from non transformed content.</thetext>

    <thetext>I am using zoom to make a flexible canvas o dom elements. So far I had to omit using scale and can not utilise the hardware accellerations of matrix transorms.</thetext>
