Debug pie chart gets stuck on screen

Note:

I do not know how I opened the debug piechart in the first place, how do I get it off of my F3 screen?

 

What I expected to happen was...:
That the debug pie chart disappears after closing the F3 menu

What actually happened was...:
The pie chart got stuck on my screen, even after closing that world it remained on screen untill I closed the game.

Steps to Reproduce:
1. Get the pie chart to appear on the F3 screen.

2. Close the F3 screen.

 

More Notes:

The chart stops updating as soon as you close the F3 screen, and will then remain disfunctional even after re-opening the F3-screen.
