Also I'd like to control the speed and i want to use it as a video. Maybe if i convert it to video and stabilize it then it's possible to fix this issue.

@jo Here is a gif with the Skia. But it is doing the same if you looking at the corners. I'd like to use it for a projection in large scale, so'd be more visible at that size

@jo hello jo,
im curious about this solution because my animation seems a bit shaky and its not about the number of frames. It looks like it always snaps the points to an invisible grid which has a lot bigger units than pixels. Thanks in advance!
