Vsplit causes vertical scrollbars to be displayed (gvim)

Question

Making the transition from Vim to gVim, I would like to disable all toolbars and scrollbars. This works for the most part, but when I open a vertical split, under certain conditions, a scroll bar pops up on the left. If you open the second picture in a new tab, you can see my vim options for disabling the toolbars/menubars/scrollbars in the bottom right window. How do I get rid of them for good?

You show what you've turned off from your guioptions but not what remains. In any case, the solution's in there. I'd start with turning off both r and R, and l and L. If the problem persists, go with

set guioptions=

and then add an item one by one (those which you need)

set guioptions+=...

This is really the best way to debug it :)

I have only =aem in guioptions, and don't see any scrollbars or anything of the kind.
