Not elegant Custom Preview in V8

The black edges are gone and they flicker when model is rotated:

not such thing with Human preview component:

Hi @Piotr,

‘Custom Preview’ has been rewritten to accommodate some internal changes in v8 and may be still differences from how it behave in v7.

This one is been fixed on 8.16.

Now like in v7 it only draws shaded geometry on Render and Arctic mode.
