Mobileweb - Background Images flashing on click

Hi All,

Got a very strange problem,

On my main window I've got a backgroundImage

However whenever I click anywhere on the screen, or try focus in textfields it just flashes

I've added a video to demonstrate its behavior

the only styling on the window is this:

"#main": {
    backgroundColor:"#f4b7d1",
    backgroundImage: "/images/bg.png"
}

"#main": {
    backgroundColor:"#f4b7d1",
    backgroundImage: "/images/bg.png",
    backgroundFocusedImage: "/images/bg.png",
    backgroundSelectedImage: "/images/bg.png"
}
