This happens for me as well. The issue shows up in Nautilus, Synaptic, Transmission, gedit, document viewer, and I'm sure more than a few other applications. It doesn't happen in gnome-terminal, chrome, firefox, clementine.
I can't find the package in synaptic to downgrade it to (I'm looking for gtk+3.0 correct?), so I cannot test the PPA just yet. Any suggestions? I am however using the scrollwheel to switch workspaces. Turning this off does allow me to scroll within the above applications, but I need to be focused on that application. If it's a background app, I still cannot scroll.
