Evee volumes strobing/flickering

I get sort of striping or strobing on my volume as the camera moves. Tried reducing tile size and upping samples. Also tried increasing light clamping. Blender 2.9 Evee. Cycles doesn’t seem to do it. The volume runs along close to a ground plane. If I disable the ground plane, the volume doesn’t flicker and looks good. Any ideas? Thanks

Hi.
These types of problems can be due to different causes, such as a bug or configuration problem.
It would be best if you share the .blend file here.
Also you mention what is your GPU and what is your OS.

I think it was because the volume was too close to a ground plane, so I rendered it out on its own pass. GPU is Radeon Pro Vega 56 8 GB, macOS 10.15.7. Cheers
