Yes, I am familiar with the right and left inputs so i am thinking Cura and Fusion filter those out.
with 3D builder, when i am careful not to move the wheel to the sides - it does stop the zoom but then it wont let me pan&scan. with lightburn however - this is more promising as when i am careful not to move the wheel to the sides (hard to do) - it does looks like pan&scan works as expected.
So, I believe you’ve nailed it. filtering those out will probably do the trick.
Many Thanks.
