Generally really janky scrolling, particularly if the image column on this site is zoomed in such that it fills the viewport.

I can sort of reproduce this on desktop with responsive design mode:

A fair amount of time is being spent in blendTextureLinearRepeat, my guess is we're running into overhead from a small image that it's being tiled many times.
