I thought I did, and I even went to check, but I thought the post I found had a different username, my mistake.
Have you found the hotfix list for 5.0.2? I’ve been trying to dig it up but haven’t been able to find it. There may be some explaination there, potentially.
If it’s MRQ rendering, I’d honestly just go with the path-tracer if you can afford it, the denoiser lowers the sample count to something generally easier to swallow. In the PPvolume, path tracing has a ‘high-quality DOF’ toggle that makes the path-tracer actually simulate DOF instead of adding it as a post-process. I used that method and it solved some strange sorting issues for me in a test.
