  I had the same problem here, while scrolling Firefox couldn't catch up and showed white just white for a short time. Then I saw the huge background gradient. The background is an image, a radial gradient, and also background-blend-mode: hue; edit: there are even more huge div's that have the same background, so there are multiple layers of gradients with hue blend mode.

      If I were you I would also consider getting rid of your textured background (https://learntemail.sam.today/static/images/texturetastic-white.png https://learntemail.sam.today/static/images/texturetastic-wh...). The little grey blobs just make me wonder whether my monitor is dirty.
