V-Core 4 400 from CoreXY to Hybrid - Surface artifacts

Hello,

I just installed the Hybrid motors, and tuned input shaper.
I previously made the same test in CoreXY.

I have seen an improvement in the fact I came from mzv, 2hump_ei (Y) to mzv, mzv at double acceleration.
But still printing the same G-Code (tower) for checking.

Unforunately now X has a uneven surface. Movement in Y plane. This is subtle but it seem that there are newer issues coming from the Hybrid mode.

Does anybody faced this kind of artifacts and found a solution? Or a methodology to tune it.

Shaper results added too.

Thank you.
