Short description of error
Specific setup of mix/add shader nodes creates horrible artifacts when moving the camera in rendered mode using EEVEE-Next
Exact steps for others to reproduce the error
Move the camera with this shader node tree on the default cube:
This is not the only way to reproduce, various other nodes other than glossy create this artifacting, but this is the most obvious.
Cannot reproduce on:
It must depend on the OS Linux + GPU NVidia
Can't reproduce this artefact. I could get some noise from moving very fast and I believe it's just due to sampling.
Could you use
Help > Save System Info
and upload the file? It might be possible that you are probably running blender with integrated graphics.Can still reproduce on

, looking at the commit that seems very strange, but I've checked many times now so I'm certain
