I just tried the nouveau driver in 4.9.0-11-generic. Now while it didn't flicker, what it did do was exhibit the very start of the problem, which manifests as subtle vertical bars in the top panel's dark brown bar. So it may not be an Nvidia problem, but a kernel problem, that may have been fixed in 4.10.

I made a video illustrating the problem: http://damonlynch.net/share /Ubuntu1610screen-flicker.mp4 Driver is from the "graphics-drivers" PPA. At this point I don't know if it's a hardware problem or software problem -- I've never seen anything like it before. I've ruled out the DisplayPort cable as a problem, because it exhibits the same problem with two different cables. The LCD is a Dell UP3017.
