This is a limitation of edge draw optimization which is based on angles between edges. If subdiv level is high, angle between edges is small and they're getting skipped. It's known limitation of this optimizer and you could work it around by enabling "Draw All Edges" in Object settings.

Thanks for the report, but would not consider this is a bug, more like a thing to be improved.

A by default completly invisible object is somewhat strange, I would say.
Since "Draw All Edges" is a "per Object Setting", couldn't this setting be changed in a way that drawing all edges is the default ?
And then make a checkbox for "Hide Low Face Angle Edges" in the Object Settings instead.
Perhaps even better, if this settings could be set globally/for all objects too, in the N-Panel under Display, e.g.
Then one could make this his individual default.


We are planning to bump viewport to a completely new level, here edges drawing wouldn't be such a problem. So don't think it'll be a good idea to change defaults now.
