35ms GPU time during scrolling near the top of the page with split-composite and image shaders standing out. Frame time reasonable when re-drawing the frame without scrolling (like when hovering over elements) so picture caching seems to be helping in these cases but the expensive parts appears to be invalidated during scroll.
