Fixed for me by the following package upgrades fixed the problem for me:
overlay-scrollbar (0.2.16+r359+14.10.20140625-0ubuntu1 => 0.2.16+r359+14.10.20140625-0ubuntu2~utopic1)
overlay-scrollbar-gtk2 (0.2.16+r359+14.10.20140625-0ubuntu1 => 0.2.16+r359+14.10.20140625-0ubuntu2~utopic1)
overlay-scrollbar-gtk3 (0.2.16+r359+14.10.20140625-0ubuntu1 => 0.2.16+r359+14.10.20140625-0ubuntu2~utopic1)
Before that, the problem actually went away by *enabling* rather than disabling the overlay-scrollbars (overlay-auto instead of normal)
