Has anyone else got tinylauncher (
https://aminet.net/package/util/misc/TinyLauncher) that can also confirm this?
In 4.4.0 the animation of the Space Invaders title screen/logo seems quite smooth when the screen scrolls up (and then back down when you go into a menu option). However in 4.9.0 (and this 4.9.1 beta), using the same config, it seems to judder a bit both going up and down.
