Bug Description
My screen is experiencing a weird "scrolling" flicker, especially while displaying blue, indigo, and violet hues/colors, such as on the default Ubuntu 18.10 (x64 Desktop) lock screen. The screen flicker scrolls up and down, with the brightest part of the flicker being towards the top, with a gradient that fades back to the original color near the bottom.
Problem occurs on any one monitor on any one video output protocol (DVI-D, HDMI, and VGA).
I will upload an illustration or render as soon as possible for better explanation.
