Scrolling issues on macOS Sierra

I'm having scrolling issues on my mid-2011 iMac running Sierra. This happens in every application and it isn't restricted to a single device, meaning this issue occurs when I try scrolling on the keyboard or the trackpad or a wacom tablet. If I try scrolling down, I will go down a page or a document and then the scrollbar will move up again once I release the down key or the scrollbar. I've tried the usual reboots, pairing the devices again, looking at the accessibility options on system preferences, but without any luck. I have installed Sierra a long time ago, so I don't know what prompted the issue. This seems to have happened overnight. Help?
