I'm now fairly certain this is actually this bug (https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/949414). The symtopms seem pretty much the same. It seems to be an issue with gtk not handling touchpad events properly
If I plug in my USB mouse I can use the overlay thumb just fine. Is everyone else experiencing this also using touchpads? Have you tried it with a mouse?
