Scrolling pages with large downscaled pictures is sluggish on pages that don't benefit from picture caching. Profile: https://share.firefox.dev/3LjkvVq I noticed this on phanpy.social (see bug 1907137) but it's somewhat tricky to reproduce because of the dynamic content. I wonder if WR could detect large downscale factors and cache the downscaled representation. Such an optimization could improve scrolling smoothness on both SWGL and on weak GPUs.
