Public bug reported:
Choppy video is also present in games: Kpatience, Mahjongg, etc.
In Ubuntu 16.04 on same computer all is smoothe and fast.
My desktop with AMD ASUS mb and GeForce 720 nvidia card:
Very choppy video, no smoothe scrolling. Drivers 440, 435, 340, 390 make
no difference.
If you'd like me to test, just email me.
Thanks,
Ken Wagner

FireFox).
