This is a bit weird. I set my project to scale outer with autofit = cover so that it displays well on different devices, and it does. uses the fullscreen on iphonex, including around the notch, and likewise on 4:3 devices like ipad.
Except my menu screen for some reason, and I can't work out why. Every other layout is perfectly fine. You can see in the piccy below, there's a lot more to the background that's hidden by those black bars.
Any ideas? I have the layout size at 320x180, but there are other layouts with this size and they don't have the black bars around them, just this one.
