I'm using Fusion developer 2.5. 280.32.
The frame width is 2048 and scrolling left right works OK.
On PC no problems at all, but On iPad there are issues:
When I run an animation (active object) and then scroll the screen horizontally (sliding finger on screen),
the game will crash if the active object playing the animation gets out of the screen and then back in.
Sometimes it takes a couple of left right movements to get it to crash, but it will always crash after this in\out of the active object.
Sometimes I won't even have time to scroll the screen back to get the object back in, and the game would crash.
If the animation (active object) does not get out of the screen, scrolling left right will not crash the game.
