EDIT 2023-02-10
Just to check if this is still happening after the window resize fix and it still is. Win10
Here in the gif, as I start to handscroll, the view jumps at first which is a bug by itself. Then as I continue to scroll, I end up two measures before the point where I started the drag.

Original post
Hand-scrolling in notation is jumpy and does not stick to the mouse cursor well. Also there is some kind of speed threshold, meaning if I move the cursor very slowly, the notation does not scroll at all.
