It seems like turning this option off only adds about a line that is 1 pixel high. I have the taskbar on top and it is almost impossible to "grab" the browser window.
If I move the taskbar down it's no problem, you just move the mouse to the edge of the screen and you can "grab" the window. But with my setup it is completely unusable. I hope there is a fix coming soon.
