I'll look into it to see if there adjustments that can be made to lower the CPU usage. The smoother the scroll is, the higher the CPU because it's going to force invalidation/redrawing as the components are moved on the screen. So one thing I could consider is making the scrolling a little less smooth by forcing a minimum time between invalidations while scrolling is active, which means the page will shift more pixels at once between each redraw.
