Bug Description
The screen experiences severe flicker when using Nvidia 375.26 on a GTX 1070 in 16.10, Unity Desktop -- but only when the terminal is in the top left of the screen or maximized, and is full of text.
I made a video illustrating the problem: http://
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.

Your system is not currently configured to drive a VGA console
on the primary VGA device. The NVIDIA Linux graphics driver
requires the use of a text-mode VGA console. Use of other console
drivers including, but not limited to, vesafb, may result in
corruption and stability problems, and is not supported.

Taking a full-screen screenshot of the problematic view (i.e. with a maximized terminal window full of text), and then viewing the screenshot at full screen, is displayed fine.
