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.

I adjusted right Y belt tension (lowered) using Spectroid on Android, to almost match the left one. Artifacts are almost eliminated. It seem mismatching belt tensions aren't spotted by the standard CoreXY belt tension test (not visible).
