Issue with "object traces" when using SSR

Hello!

I'm experimenting with using SSR by adding <SSR /> to the Canvas imported from @react-three/postprocessing. I'm noticing some thing odd, which can be best described as objects leaving traces, while moving the camera around. I tried to capture as much details as possible in a post I made on the threejs forum. I'm currently lost in trying to understand what could possibly be causing the issue I'm seeing. Thanks a lot for the guidance in advance!

This is smearing from the temporal resolve of the SSR effect which is no longer maintained in favor of https://github.com/0beqz/realism-effects. Its v2 branch has a very stable denoiser which I'm delaying #211 for, which SSR would be specular-only.
