Random white bar at the top of my screen

So, I just have a minor problem.

My Galaxy S4, from Sprint, has recently had a white bar blocking the notification bar.

The bar basically looks like this: |P: 0 / 1 | dX: ##.# | dY: ##.# | Xv: ###.# | Yv: ###.# | Prs 1.0 | Size: 0.03|

The #'s change whenever I touch my screen. Also, whenever I touch my screen and move my finger around simultaneously, there is a blue line showing where I touched, and it remains until I touch the screen again. How can I remove this? It's very obtrusive.

Fail, it's a developer option that I misclicked.

The white bar - where does it come from please. I don't know what I clicked to get it up there but I want it off. Please advise.
