I'm pretty sure this is a issue in Gtk+3.0 due to a fix put in affecting mouse wheel scrolling. I have a potential fix in my PPA at ppa:townsend /gtk-testing. Could someone affected by this bug please try my PPA and let me know? If it does fix it, then I'll continue to try to upstream this to get it fixed.
