Marlin bugix 2.1.x Version has a bug if you want to print fast and have ABL activated:

• The steppers are starting slow down/stuttering when crossing the Meshlines. Also printed blobs are visible at this spots.
• High Jerk or junction deviation setting are not the solution in this case.
• The display menus were lagging at fast printer movements.

New version 2.1.2.1 is working fine.

Status Screen with black background(is set to blue on version 2.1.2.1)
