    I have a problem setting up reflection probes in my scene, we want to get them to work since our skybox is affecting meshes in shadows.

    We're using HDRP in Unity 2021.1.6f1

    After baking it seems ok at first but after i move my camera around and change its view direction reflection probes act like they pop in and out of existence, which manifests itself as shadows and speculars flickering around.

    We do use Screen Space Reflections as well, for reflecting stuff in water puddles etc.
    Turning them on and off does not resolve this issue.

    It works like that for all the materials and does look pretty bad, i tried playing with their blending distances and influence boxes but it never did anything, I ran out of ideas and don't know how could we fix this.

    Honestly just rotating camera around makes them glitchy, please help.

    Here is a webm presenting this issue: https://webmshare.com/play/JbXzL

    So i tried setting reflection probes limit to the one above an actual count of my probes, it didn't work.

    I also tried disabling other types of reflections and it still flickers.

    I've played with project graphical settings and nothing really worked.

    Is it just that those reflection probes don't work?
    Somebody please help.

    2021.3.8f1, problem still exists, Unity please help!!!

    This is annoying AF, however I noticed sometimes it helps when you make the reflection probes completely new.
    Sometimes they work until they don't.

    Obviously, this isn't a practical solution at all - please do your job and fix this, Unity!
    Unlike in the BIRP, Reflection probes are a necessary lighting tool in the HDRP, so I find this unacceptable :(
