In V4.1.1 there are some cases, where Solid Layers are created between Inner Perimeter and Infill.
It depends on the geometry, in my example on the angle of the inner hollow cone and does not happen in V4.0.1.
See screenshot, left is V4.0.1, right is V4.1.1.
And please have a look at the extra infill arcs at V4.1.1.
I know there were some changes in V4.1 and some improvements in V4.1.1. This seems to be a left over.
