Comment 14 for bug 766660

I don't know if UX/DX teams actually meant the overlay scrollbars to be specific to unity or applicable to everything. From my POV the classic session is not meant at all to be a "vanilla GNOME" kind of thing. It still has indicators, compiz, notify-osd, and all other Ubuntuisms, and as overlay-scrollbar does not make any attempt at all to be session specific it seems straightforward for it to apply to classic as well.

However, stracciatella-session should of course disable the overlay scrollbars. I added a task for this. This is a small and straightforward change, and thus SRUable for natty.
