I'm having some troubles trying to make the game appear correctly on the Arcade.
I'm using Scale Out, and when requesting the full screen, the game misalign on the Screen, appearing only the first 1/4 of the game screen and a white background around.
What I can do?

That could be the correct display, depending on your settings. If you're using unbounded scrolling, try scrolling to the correct position every tick, so even when the screen changes size it's still centered where you want it.
