Endless scrolling causing problems with physics

[Slimjimmyb]

Hi,
This is a very specific issue, I'm building a physics-based game and I want the level to go on forever, and using virtual-width -1 works. I know there are other possibilities, but I'd like to take this approach if possible because it's logical, interacts well with parallax scrolling and doesn't involve a huge amount of work relocating objects when you reach the end of the map.

HOWEVER - it only works fine using non-physical platform movement. Any physics object stops handling background collisions the moment you go off the conventional frame edge (yes, handle background collisions outside frame area is on). I suspect this is because of the way the physics engine 'adds background to the world' but there doesn't seem to be an option to refresh this when 'the world' moves on. It also has problems the moment you traverse into any virtual width, not just with virtual width -1. Added backdrops in the virtual frame DO add to physics world but don't refresh the non-colliding area, and I don't really want to be creating endless backdrops if I can avoid it.

Any ideas for solving this would be hugely appreciated!
Many thanks,
