Comment 18 for bug 608124

I've updated the bug's title to reflect the change from the initial bug-description, since the old wasn't closed and a new one created. Like mentioned the initial bug was filed against the clutter/mutter-implementation of unity and in between there have been many visual design-changes to the scrollbars, unity ported to a new foundation (compiz/nux) and the design now demands overlay-scrollbars to be also usedin the dash.

Since the dash uses nux, this needs a nux-implementation of overlay-scrollbars. The initial implementation for the rest of the desktop is gtk+-based and can't be used inside the dash.
