    screenspace shadows flicker in deferred (not in forward).
    hard to capture in a gif but if you look closely you will see it.
    also present in 2021.2.0b4.
    bug filed (case 1354681)

    it seemsthat in deferred the screen space shadows get corrupted as they sample an empty cameradepthtexture.
    which is nothing astonishing in this frame as nothing has been rendered so far to the depth buffer?!

    enabling decals as well fixes the issue as now we get a depthnormalprepass:
