This is a laptop; the laptop screen displays some colors as flickering
vertically striped patterns, which IRC/imirkin diagnosed as unneeded dithering.
Disabling dithering with xrandr fixes the issue.

So nouveau is correctly turning on dithering based on the information available to it. However perhaps that information isn't trustworthy for fermi+. Or perhaps there's another bit somewhere. -- You are receiving this mail because: You are the assignee for the bug.
