iPhone 5 Fullscreen and Letterbox Scaling

<img src="http://i.imgur.com/3HSc0uh.jpg" border="0" />

Firstly, before anyone points me to the tutorial on supporting multiple screen resolutions, let me say that I have read it and that my game's resolution is 1136x640, or exactly the same as the iPhone 5's resolution.

This is what I see when a user fullscreens my game. Does anyone know what causes this?

This is what it looks like without full-screen:

Anyone have any idea what's causing this?

It looks like full screen is larger than the actual resolution... are your window and viewport sizes set the same?

Also, I love the UI on that! Are you going to do the Shield Power and Ship health to match?

Is there a way to set the viewport size to a certain amount?

My window size is 1136x640, or exactly the iPhone 5's resolution.

For the NG game jam, I doubt I will be able to get the ship health and shield percentage to match.

Seems to be working now. All I had to do was turn off 'Hide Address Bar', and the full screen doesn't have the black bar at the top anymore!

Can we update the tutorial on web apps to not hide the address bar to avoid the fullscreen problem?

I would like to say this issue still persist :( Reported bug.
