Bug Description

If you disable the blacklisted emacs in overlay scrollbars, you'll see how they are not working. If you grab them, you can't scroll the page (but the thumb moves)

Overlay scrollbars still break in the same fashion in emacs development snapshots and, considering that the release of 24 is nigh, presumably will in 24 as well. I've attached a patch adding emacs-snapshot{-gtk} and emacs24 to the blacklist.

More discussion here http://bugs.freepascal.org/view.php?id=19266, eg

The overlay scroll bars are the culprit. Ubuntu is maintaining a blacklist of applications that don't work with these new, IMO ugly, scroll bars. On an almost daily basis apps are added to the blacklist. Examples: https://bugs.launchpad.net/ubuntu/natty/+source/overlay-scrollbar/+bug/770304, [^] https://launchpad.net/ubuntu/natty/+source/overlay-scrollbar/+changelog, [^] etc. The blacklist is apparently not a simple file that can be edited.

To disable the overlay scroll bars for all applications(from terminal):
sudo su
echo "export LIBOVERLAY_SCROLLBAR=0" >> /etc/X11/Xsession.d/80overlayscrollbars

Log out and you are back to the old scroll bars.

This is ubuntu unity + liboverlay problem not fixable by us. export LIBOVERLAY_SCROLLBAR=0 is solution.

FWIW, this is still an issue with Ubuntu 18.04 and emacs 25.2.2
