Why it happens
Coplanar geometry or a large far/near ratio leaves too little depth precision.
Check / fix block
FreeCheck: camera.near at least 0.1 and far/near at most 10000; separate coplanar faces with polygonOffset or 0.001+ of distance. A full turn shows no stripes.
The library itself is public. On a card, the first check is free; the rest and the contact sheet are Pro.
