Why am I getting texture bugs when using my lenses in snap cam?

Lenses are fairly simple, a png image object on orthographic cam for blue screen background, default material. And a png on a headbinding that has face insets on the headbinding. Works fine in preview, and on mobile, but not in snap cam... delivers black and purple checkerboard...

I confirm we have the same issue. Filters works fine in preview and cellphones, but have artifacts in Snap Camera. Thread: https://community.snap.com/snapar/discussion/1639/glitches-when-i-publish-my-lens#latest
