The autoscrolling has no problem when scrolling on a steady speed. But the problem occur when there is change in scrolling speed and direction. The problem is more apparent when increase the scrolling speed slowly. However you can't see the problem if the increase/decrease in scrolling speed is too fast/slow. The problem is apparent on some webpages and less apparent on others. You can see this on some manga websites, for example,
