Extra gap on right side of screen?

So I am having this problem both on the GS previewer and when testing on devices.
There seems to be an extra 1-2 pixel gap on the right side of the screen.
Shown below. (You can see a thin black line as if everything is pushed over a few pixels.)

I have no idea what is causing this. In this particular shot, I set up 3 plain actors, the first is display size width, the second is the background size width, the 3rd is the background X position.
Everything matches up in terms of sizing and position but why am I getting this gap?
I've looked into the camera settings, scene settings, I've set the background to tile horizontal and nothing.
Any ideas?
