The artifacts appear due to some vertices in the mesh being disconnected and moved slightly (even a 0.00001 shift in a disconnected vertex’s position can cause the artifacts to appear):

The gaps formed by the disconnected vertices then get the Highlight outline applied to them.

The issue should be fixable with merging the vertices by distance in Blender.

I see, I was thinking that it might be something wrong with the mesh but I wasn’t sure. i will keep that in mind for future reference. Thanks!
