The best fix I can suggest here is for the user to copy the depth texture and use that during the UI rendering.
Scene Depth materials are rendering completely black.
See the attached screenshots for comparisons between 4.15.3 and 4.16.
This issue did not occur in 4.15.3, this is a regression.
Result: The material drawn to the HUD is completely black
Expected: The material would have the same appearance as in 4.15.3
