System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1650/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.09

Blender Version
Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: 0f45cab862
Worked: (newest version of Blender that worked as expected)

Short description of error
There's one light object in the scene and when rendering, it caused a pixelated fog. So I tweaked the tile size to 2 px and though it fixed those pixels, now I get weird flashing in random places. Video .

Exact steps for others to reproduce the error

Set Tile Size in Volumetrics to 2 px, anything other than 16 px will cause the flickering.

[Based on the default startup or an attached .blend file (as simple as possible)]

Hi.
This is apparently an nvidia driver for Windows bug

Hey, that's soo weird. I've experienced this on my different scene a long time ago, but I didn't bother reporting it, but I got it again so I thought it must be a bug. So as far as I understand, there's no fix to this?
