Title:
Severe screen flicker on Unity when terminal maximized
Status in xorg package in Ubuntu:
Fix Released
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://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.
