I have made a scene with an ocean. I used glossy shader as its material. When I render it I found weird artifacts at the bottom of the 360 render. So I made a new blend file to test if the issue is with using the gloss shader or if the issue is with 360 renders. Using a sphere with a Voronoi texture as displacement. I used a glossy shader on it. And yes the issue seems to be that reflections get weird when you do a 360 render(paranomic).
Please help me understand what the problem is.
Edit: Unfortunately, the render is above 4k. so it's not possible to upload it here and if I downgrade it to low res im pretty sure u won't be able to see the artifact. So here: https://youtu.be/C7360TeoJ8I I uploaded it on youtube. Is it possible to upload a blend file here?
