Comment (by strk):

 The curved part of the ring is almost a line. Default linearization using
 32 segments-per-quadrant end up approximating it with a single straight
 line.

 I guess the fix here would be to enforce a minimum of 2 segments for any
 non-closed curve and 3 segments for a circle. Dunno if that should be the
 default or a parametric configuration.

 The work done in #3772 could help in that it allows specifying
 linearization constraints in different ways and allows specifying a flag,
 but there's no specific flag to ensure at least 2 segments are used per-
 curve.
