Fullscreen slideshow not working properly on Chrome

Question

Firefox, explorer and safari return no problems, but on chrome, whenever I scroll down there's background fill going up over the slideshow until it's fully covered.
What is happening here? I tried a lot of things but nothing works.

Answer 1

Ok
I have a fullscreen slideshow on the bottom layer. On the higher layers there is multiple content with text, slideshows, thumbnails etc.
The idea is to show always de fullscreen slideshow as a background.
As I said, it only crashes on Chrome.
When I start scrolling, the slideshow starts getting covered from foot to head by the browser fill. As if the browser fill was being displayed over the slideshow.
It's not that the slideshow scrolls up beacuse the images stand still all the time until they are fully covered by the browser fill.
Thank you.
