My guess is that the box get scaled so that the horizontal line of pixels is removed. I think you can avoid this by using the Slice 9 feature of box nodes.
You mean about the background node? You can set Size Mode = Manual and set Size to fit the display size and set Adjust Mode = Stretch
The small rotation in combination with the Size Mode could make it so that the top part rotates out of the render area (depending on your camera and scene set up). If what britzl recommended didn’t work I would try to zero out the rotation.

I didn’t even notice the rotation. That could indeed also be a problem!
