When toggling fullscreen on MB Pro Retina 15 - a red bar appears I experience a red bar appearing right on top of my screen everytime I toggle fullscreen on. In addition to that the mouse seems to be shifted by about 50 pixels(the height of the red bar appearing in the top). For example I can click on a button while placing the mouse 30 pixels above the button. 

When I exit fullscreen it disappears.

My machine is a 2016 MB Pro retina 15. The machine is running OSX High Sierra version 10.13.3 and Blender version is 2.79 2017-09-11. 



I'm helpful for any insights.

The solution was to resize the blender window to a smaller height. And toggle fullscreen after the window height has been decreased.
