Equirectangular render flaw

I noticed this flaw in equirectangular rendering which causes this weird line because of shade differences. Here is an image of the flaw.

I noticed this in the Pannellum viewer. Please suggest if there is a solution for this. I have been picking camera angles to make these not noticeable but no matter what I do, it exists in the renderings.

That’s provoked by the denoiser, you can give more samples to the render or denoise later in comp and overlap a bit the layer to avoid this, but there is no solution right now to that apart from solving it in post or render more samples to avoid the problem.
