UFO Following the Cursor

In model and paper space, there appears to be two lines of text extremely small in size that follow the cursor everywhere it goes. It's too minute to ascertain what it is exactly. It isn't causing productivity issues, but it's strange as hell. I'm not sure if I 'fat fingered' a combination of function keys to cause this. Curiously, CTRL/ALT/Print Screen and pasting into Word, the phenomenon is not observable. Any help is appreciated.
