As we all know, Ubuntu 18.04 has a few scrolling issues. But I notices something really interesting. In general, I don't have many problems with scrolling. But I have one which is very annoying. When I scroll in a different application(in my case, it's always reproducible with LibbreOffice), and then quite quickly switch to Chrome and move cursor, the page jumps up or down depending on what direction I was scrolling in LibreOffice.
