Public bug reported:
I first discovered this problem in Mint 18.1 Cinnamon (64-bit) and Mint
18 XFCE (64-bit). I enabled Glamor (and thus, it seemed DRI3) and tried
turning off smooth scrolling and/or hardware support in Firefox, but to
no great avail. Interestingly, scrolling worked nice and smooth with a
Geforce FX5200, 128MiB - an older, inferior card running on nouveau.
I installed Ubuntu 16.10 to try with the latest software and
drivers..and the problem still remains. Scrolling is stuttering badly if
scrolling in a full screen. Scrolling the Facebook feed the problem is
less, but noticeble. Youtube-videos play abhorrently slow.
