System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2020-11-06 19:20, hash: d2c102060d
Worked: 2.90.1

Short description of error
It's the second time that when I try the new 2.92 alpha, when I render a scene even fairly simple, a couple of buckets, that just finished to render a part of the image, go back there where they just finished and add some noise to it. This time it also happened that they erased part of the background. Unfortunately it happened only two times while other times the render went fine, so I'm unable to reproduce, I can only say that Optix denoiser is enabled.

Exact steps for others to reproduce the error
I don't know how to reproduce, I only think that it might be connected to the new "GPU tiles stealing feature" or to optix denoising.

Some problem is occurring on your graphics card, not completely using the CPU of your graphics card.

Actually I just found a reported bug that is exactly my same problem: https://developer.blender.org/T82351, guess I should've dug better!
I'd delete this task but I cannot find a way to delete or merge it with the other one.
