This bug also appears on my MAC M1 Laptop.

Printer

Bambu Lab X1 Carbon

How to reproduce

Load the attached project, labeled holes_bug.3mf
Slice the project
Observe the objects with the perpendicular holes where the inner wall are plugged vs open.

Actual results

You will see a band around the area of the holes on the throughout holes on the objects without wall plugs. The objects with plugged walls are ok with even surface.

Expected results

When slicing an object that has through holes, the inner face should not add any thickness. This is very annoying when designing precise slip fit objects. I was able to find a work around by plugging the walls with a very thin wall which the slicer opens up because it's too thin, and this fixes the issue.

****Important Update:

I discovered that the issue is introduced when using 'X-Y hole compensation' and 'X-Y contour compensation. ' individually or both. Setting both to 0 (the default) it slices without issues.
