Short description of error
Hi!
in scenes with a great deal of transparent objects the depth pass can be noisy.
To avoid this problem I've found out that the denoising depth pass (deonoising data) was a viable solution (I usually combine it with a map range node to control the depth gradient).
In the 3.3 version of blender this is no longer true.

If you open the same file in the 3.2.2 version and in the 3.3 you'll see the difference.
Hope I didn't waste your time
Thanks anyway for the amazing job!
Kind regards
Fabrizio
