I'm having an issue with the display of an uploaded background, but only when viewing the site on a portable device (cell phone). I initially changed the background image to one of my own and while it worked great on a computer, the image and the slideshow are all you see on my smartphone. It appears that the page loads correctly, but then is quickly overlayed with my background image and the slideshow. I then switched back to the original background image that comes with theme, and the same thing happens. I've cleared my browser cache and cookies with each change, went back to the original slideshow images, too, and the problem remains.
