    It looks like this issue is not resolved:

    I get a black screen when the camera stack is enabled.
    Once I turn off MMSA on the main camera, everything renders correctly.

    The issue was Observed in the following Environment:
    macOS Monterey 12.3.1 (21E258)
    MacBook Pro 15' 2018
    Radeon Pro 555X 4 GB

    URP v12.1.6
    Unity 2021.2.17.f1

    I use Post processing with Bloom, Vignette

    Global Fog is set to Exp

    Still a thing in 2022. The HP Elitebook I am on is where the issue persists on the web. I believe it has something to do with the graphics card specifically. Truthfully I do not know what is causing it, I am going to attempt a new cam structure today. Any data on this issue would be super helpful.

    Just to confirm this is not working still. Only the first camera draws, the rest are black.

    Unity version 2019.4.10f1.
    URP Version 7.5.1
