I see a sqaure following my dragging on my surface 2

[AJ98]

Every time I drag my finger on the screen of my surface I see a square representing where my finger is. How can I change that ? Thanks

What app are you running when you see this square?

the box shows up every where, no matter where i drag my finger or which app i am using. it is like presentation purpose,
