Some anomalies observed when surfaces are enclosing volumes or overlapping certain ways.
In most cases it does not https://clara.io/player/v2/1e0c3009-dabc-4d0c-af91-8dec5b851263?wait=true
Mostly happens when the surfaces bound a volume https://clara.io/player/v2/4d432c4e-2b0e-4c9c-9fee-18ff8517d6f8?wait=true
Problem occurs also in OPENGL and Sketchfab https://sketchfab.com/models/d7542d0179064a208a1c952dba028376
Three.js folks told me to post here
