I've tried helping @carcamerarig on this issue, maybe I can give my take on what's going on. We believe we have homing with stallguard figured out, but that's not the main issue.
The issue is during fast moves, the printer will stutter causing a thump sound, resulting in a layer shift. The nozzle is not hitting the print or other obstruction.
I thought originally this may be caused by the switchover from stealtchop to spreadcyce. However forcing the machine into spreadcycle after homing did not alleviate the issue during a print. @carcamerarig Can you post a link to the video showing the problem?
