Problem occurs with notebook and multi-vendor desktops with ou without offboard video card. If i connect to the session with one screen it works.ĬTRL+SHIFT+WIN+B and signs back in it works. If i disconnect the user from the session and they log back in it works.

If the user signs out, and signs back in it works. It's just when the window is maximized, you can stretch it to 'full screen' by hand and its fine too. Right clicking on the empty or black / white space on top of that window you get the context menu of the desktop. We have different Users with a strange behaviour - if they maximize a window tested with IE11, Acrobat, Windows Explorer, google chrome they get an empty or black / white space on top of that window.
