QR code - When lasering the same QR code on multiple cutouts at one time machine goes crazy

When lasering more than one QR Code generated in Lightburn with XTool D1 Pro 40 watt the laser prints parts of each QR code that are in a row before completing them the laser speeds up and goes off the design. I can laser 1 at a time no problem. Has anyone else had this issue.

Is Fast Whitespace set too high?
