Sounds like both problems stem forth from the layer your using/placing things on, and their respective scale settings.
for instance, with problem 2,
Add a new top layer, set scale 0, and paralax 0,0
add an item in the box with dashes somewhere (top left on your layout, the project viewport), then add anchor behaviour to that object.
I believe for the background its something the same.
Perhaps disable the paralax, or even turn off the scale.
