Safari iOS fixed position background scroll glitch on published site


In the designer everything looks dandy, but specifically on Safari on iOS, whenever the address bar disappears, it takes 1 second for the browser to readjust the correct height of the background, leaving a bit of a white margin, which looks really ugly.

Is there any way of sorting this out with custom code?

Many thanks!

PS: The white colour seems to come from the body, even though I set it as transparent. However, if I set it to another colour, then instead of white, the address bar will leave behind that colour for 1 second. X_X
