The screen is flickering in so much as there is a very faint shimmering effect. This is usually the effect of dithering which adjusts the pixel color values rapidly to give the impression of colors that are not normally present. This effect is welcomed if using a low quality display however for certain indivduals causes significant discomfort. Can it be confirmed that any form of dithering is enabled by default in Ubuntu and is there an option to turn it off?

After research online and talking with a community at LED Strain (https://ledstrain.org) it is believed the issue is caused by dithering being enabled on Ubuntu. There is no known way turn off all dithering by default and would like an option to turn off all dithering to avoid discomfort.
