Volumetric Fog causes corruption in Render Target

I changed the Capture Camera’s Z height from 0,0, 2000 to be dynamic to the characters Z position (with an slight upward offset. This greatly reduced the artifacting to be much more rare, though still occurring here and there. But If anyone knows why the fog would cause this artifacting in the first place I’d still love to know. ( I have 1080Ti if that is relevant).
