Here's a screenshot showing the the menu and tool bars in Emacs without
your patches (left), with patches and menu-bar-scrollbar set to
`automatic' (middle) and set to nil (right):

I don't know how to grab a screenshot with an open menu -- as soon as
the menu loses focus (needed to run the screenshot program) it
disappears.  So I photographed the screen and grabbed a screenshot of the
images to reduce the size, though it's still more than 500kB and the
quality is poor -- sorry, but maybe it's good enough to see the issues:
