How to reproduce

Slice a vertical cylindrical tube with OD 10mm ID 8mm, enabling precise wall. 0.5mm line width. The attached project file has this as a protrusion above a wider part (the wider part does not exhibit any issues)

Actual results

An inconsistent diameter cylinder is sliced, with some regions that have two walls and some with one. When printed this results in an uneven vertical cylinder with some areas having a larger diameter than others

Expected results

The cylinder should have the same wall count at all layers and be uniform in diameter through its entire length. Disabling precise wall produces this result with two walls on every layer
