Marlin 2.x new jerk causing weird stuttering issues

I so have replaced one of my old board with the mks v1.3 and have been working on setting up marlin 2.x

I got everything to the point that I can print but when printing I noticed that it would break up long linear moves into multiple segments which seems to be intended for use with bi-linear bed leveling. The real problem that I found is that if I don't set #define classic jerk then at the point between segments I get bumps along the surface where its visibly pausing and oozing.

I tried adjusting JUNCTION_DEVIATION_MM up from 0.02 to 0.04 to 0.1. This helps with the long linear moves but curve segments still end up with a slight pause and oozing.

You can see the issue during print in this quick video. I have also attached a close up of the part where you can clearly see the issue.

So I'm just curious as to what I may have missed in getting it to work with the new JUNCTION_DEVIATION_MM setting rather than #define classic jerk?
