Created attachment 280952 [details] [MOVIE] jumpy zooming It should be centered at where the mouse cursor is, but it drifts to the right or left if you are slightly off center. See the video. I think we need to add or increase the hysteresis to be more up/down left/right than the record-based timelines. This is because those timelines give much faster feedback so you can adjust your trackpad movement easier. By comparison the rendering frames timeline is jumpy.

I think we have a similar bug with normal timeline zooming getting off from the mouse.
