Example URL:
http://drifted.in/other/iframe/

Steps to reproduce the problem:
1. Open http://drifted.in/other/iframe/
2. Switch between Page 001 and Page 002 by clicking the links

What is the expected behavior?
There is smooth transition between pages.

What went wrong?
There is a lag when updating the content in which the white background is visible which yields to flashy effect. That delay is rather random, sometimes minimal, sometimes quite disturbing. In my real content it takes almost 1 sec which is unacceptable for production.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? N/A 

Did this work before? N/A 

Does this work in other browsers? N/A 

Chrome version: 51.0.2704.103  Channel: n/a
OS Version: 6.3
Flash Version: Shockwave Flash 22.0 r0

In both FF and IE the another approach seems to be used - not removing the old content until the new is ready.
