Comment 2 for bug 1316613

I've discovered the package: overlay-scrollbar, and the file: os-scrollbar.c is implementing this.

http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/overlay-scrollbar/trusty/view/head:/os/os-scrollbar.c

Would it be possible to check the session name (or look for Unity's dbus session name?) as a condition to apply this? I don't think blacklisting is maintainable here.
