Public bug reported: 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://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.
