Content intermittently disappearing revealing objects underneath

I have an issue that seems to effect safari only.

On my design, you scroll down the page and the least section reveals the footer from the bottom up. I have this set as a sticky so it is always present but behind the rest of the content. In safari, the elements that sit on top randomly disappear to show the footer long before you reach the bottom.

I have a similar issue with the parallax effect on the home page. I have 6 images that flow over some text (“Say hello to the game changes…”) and only half of the image is displayed briefly before becoming complete. I have them set to ‘load with page’ and this happens in chrome

Not sure if its a setting or how I’ve structured my page (or something else)

thanks in advance.
