Flickering Volumetric Fog

Searched but not really a solid answer.

I am using Volumetric Fog in a Exponential height Fog Component.

If I set Viewport Type to Cinematic Viewport and view thru a placed camera, the result is flickering volumetric fog in the distance. I can disable it by simply unchecking Volumetric Fog in my Exponential Height Fog or viewing thru the Default Viewport.

Is there a command console setting perhaps I can try?
