Hi Luke,

Wow, seems you found a very obscure bug! Interesting.

Ok, did you try adjusting the background properties for mobile devices?

You can adjust this at the bottom of the style.css file on line 1908.

This is the CSS code to adjust,

.hero,
.testimonials,
.calltoaction,
.newsletter {
background-attachment: scroll !important;
background-size: cover !important;
background-position: center top !important;
}
