Created attachment 462579 [details] Minimal bug reproducer As the title says, overscrolling beyond the page limit either up or down causes high CPU usage. This goes away if scrolling back up/down after overscrolling. This does not happen when enabling enable_back_forward_navigation_gestures. It can be reproduced with minibrowser, as well as a minimal reproducer I'm attaching to the issue. To see the issue go away in the reproducer attached uncomment the line saying self.enable_gestures().

It's reproducible in minibrowser as well, so no need for a separate reproducer at this point. :)
