Hey there! Thanks for the feedback - I recently started to notice this as well so I've been putting more focus into improving overall performance and scrolling! This is still a big work in progress so it might take a while before all these improvements make it out into a release.
For a bit of background, most of my time developing Thunder has been through an iOS device (as that was the only device I had access to). On iOS, I would say the experience is generally pretty smooth. Only recently did I gain access to an Android device where I finally started to notice some of the stuttering that you're mentioning.
