Windows 10: Rectangular Box in Upper Left Corner

I believe I accidentally generated this rectangular (not square) box while I was learning about the Magnifier. This rectangular (7.5 cm X 4.3 cm) box causes whatever is located underneath it to be slightly whiter than it normally would be. Everything functions properly while 'inside' this box. I have tried to 'ungenerate' this box by manipulating Magnifier but to no avail. I have investigated several forums/BBs/KBs but found no solution to my problem. What investigative step do I take next to solve this problem?
Thank you.

a small white rectangular box with "Minimize"

A small white rectangular box with "Minimize" in it remains visible in the upper right hand corner of my screen. How do I get ride of it? why is it there?

 

@NurdBurd, I've just turned on Magnifier (1607 rtm) to see what you mean. Somewhere on the screen you should also find a 'magnifying glass' icon. Click on it and it will briefly become the control window for Magnifier.





After clicking on the magnifying glass, close it from here:

 

Howdy Bree,
I don't see a magnifier glass in the upper left corner. Just to make sure I was not overlooking it, I changed my "Change the size of text, apps, and other items: 125%." Then I went to the High Contrast area "Choose a theme: High Contrast White". Even after those two steps I still don't see a magnifier glass. I selected The Magnifier from my taskbar and indeed I saw the magnifier glass. When I used the magnifier glass, the recently generated magnifying area was deleted - but the area in the upper left corner remained.
Is it possible to remove The Magnifier from Windows and then reinstall it? Or perhaps, a larger section of Windows containing The Magnifier and then reinstall this larger section?
Thank you.
