MATLAB: How to avoid rrbox to generate black root window

Question

Using the simple program

    figure(1);
       set(gcf,'Units','normalized')
       k = waitforbuttonpress;
       rect_pos = rbbox;
       annotation('rectangle',rect_pos,'Color','red')

and press the mouse button in the figure, all above the cursor becomes black (sometimes some old figures and part of Matlab IDE is visible)

ones I release the button and move the mouse over black parts, they return back to normal.

I'm using 2016b on Windows 10

Some advice on how to proceed is appreciated
