Color Dropper fill and outline icons appearing on Screen

is any one else having this issue?

I will be working on a file and then the little square icon that appears when you use the eye dropper tool (solid color square for fill and outlined square for outline color) will appear on the screen.

the only way it will go away is if you choose the eye dropper tool.  Refreshing the screen does not get rid of it.

it does not print, it does not export-- but it bugs me when I have created a masterpiece but there is a little square on the screen covering a portion of my artwork.  This only happens in CD 2017.
