Little white home screen marker

[Jason Smiley]

I have noticed this before, but cant seem to remove it. It is a little icon that marks the home screens. When on the main page, it hovers over where phone tab would be (far left) I know I have got it to go away, but not sure how. It will move right as you slide the screens over. Anyone know what this is, and how to remove?

It's just to let you know what screen you're on....most custom launchers will allow you to remove it.
