I'm not aware of any rule.

The scene renders fine with the current v3.8 master branch.

You don't have a cubic sweep, but I think you are very likely(1) hitting 
a closed(fixed) issue for a problem Yadgar reported and Christoph fixed 
back in 2017.


(1) - I don't have a compile handy at the fix commit to 100% confirm it. 
In any case, the current v3.8 is OK.
