Face Mesh in Unity acting Weird

I am working on a face-tracked project with a face mesh. It was tracking well and seemed to be working OK; however, in the last several attempts to preview, I see what’s in the gif below a black, stuttered head outline in the scene window and no mesh in the game preview. I redid the project from scratch, worked for a bit, then did the same thing again. Does anyone have any insight, or maybe had this happen before? Could it be a Z-fighting issue?






Attached are my inspector panels for the game objects.

OK, so the mesh issue was a scaling problem. It was sitting below the mask. Still interested to hear any thoughts on the stutter black mask effect happening when I press play.
