What are you seeing?

After a window is maximized it gets an empty or black/white/gray space on top of that window. Issue is observed on Internet Explorer 11, Adobe Acrobat, Windows Explorer and Google Chrome.

Right clicking on the empty or black / white space on top of that window you get the context menu of the desktop. 

It's just when the window is maximized, you can stretch it to "full screen" by hand and its fine too.

If the user signs out, and signs back in it works fine again.

CTRL SHIFT WIN B and signs back in it works fine again.

This is a strong indicator of an issue with the Operating System.
