It’s a known I received many feedbacks on this particular issue, for example [this one](https://forum.nomadsculpt.com/t/black-artefacts-all-through-model-in-pbr-mode/2072/6)  
It only happens on the Air 4 (that I don’t have).

Can you confirm the bug is still happening when you have:

- smoothing shading on (Settings menu)
- no lights/shadows
- try disabling “Buffer reuse” in the Interface menu

Otherwise rebooting completely the iPad usually fix the issue from what I heard, but only temporarily.
