On my website i have added so the "fixed" header only is visible when user starts to scroll up. When page loads it shows the "basic" header and when user scroll down the header disapear but as fast the user starts to scroll up, it's visible again.
The main issue is, when i start to scroll the "fixed" header shows really quick before being hidden, please see screenshot here: http://imgur.com/yz3px4I

This is just at the second u start scrolling, it shows really quick and then it's hidden.
