Strange bug. Maybe a Factorio bug.
I turned my macbook to "Render in native screen resolution".
After restarting the game now shows a vertical scrollbar in the center of the screen (exactly over the character) . I can scroll that bar up and down, but no way to remove it.
I figured out, that when I turn of this mod, the stripe vanishes, so the simplest guess is, that it comes from here. Sorry if not. :)
