maybe I am too stupid too find this in the preferences or it is really a bug. When I reopen the MIDI editor in the lower zone or switch tabs in lower zone and come back to the MIDI editor, the vertical scroll positions changes (it always scrolls up to with a certain amount, depending on the vertical zoom factor).
This behavior only happens when the vertical zoom is greater than 0. (>+)
I would except that the scroll position in the editor doesn’t change at all when closing and re-opening it.
Looking forward to your feedback and your experiences. Can you replicate this behavior?
