@Andreas_Hegenberg version 6.311 has fixed the jumping. It seems that a side effect of it though is that during the same process (scroll in one direction, then immediately scroll in the opposite direction) the ease out (for lack of better words to describe it) is now absent, meaning the scrolling stops abruptly without overscrolling just a bit and gliding to a stop as it does when just scrolling in a single direction.
Edit to add that this is also the behavior all apps now, even the system apps.
