Too closer the edge of the screen,the easier it is for problems to occur

[jujun]

When I use Beyond or LD2000 software to edit special effects at the edge of the screen, or when I use a moving tool to move a point to the edge of the screen (as shown in the picture), I find that the galvanometer of my laser light is prone to bouncing, which in turn leads to the galvanometer not working properly, resulting in graphic deformation. Regardless of whether I set the projection zone to 100% or 50% in the software, this situation still exists. I wonder if everyone has the same experience, and what is the reason for this?
My scanning galvanometer is 30k.

If the problem persist in both applications, then I suspect something might be wrong with the scanner set. Or at least with the ranges set on the scanner driver.
