    Why is this issued listed as fixed when it is clearly not and hasn't been for a while?

    "Uninitialized" does not mean "don't clear", https://docs.unity3d.com/Packages/c...s.universal@15.0/manual/cameras-advanced.html "Note that the contents of the uninitialized color buffer vary by platform."
    You can't have multiple "base" cameras with "Uninitialized" background and expect them to combine into single image, it's undefined behaviour.
    To achieve what you want you need to use first camera as "base" and then other cameras have to be "overlay": "an Overlay Camera receives a color buffer containing color data from the previous Cameras in the Camera stack. It does not clear the contents of the color buffer."

    Thanks for your reply. I tried your method but still have problems.

    The original problem is there are two cameras in the scene.

    The first camera is for UI:





    The second camera is for 3d model.





    Then I want to combine two cameras like this:




    In the editor it works. But it doesn't work after build to Android / iOS devices.

    If I set first camera to "overlay" and second camera to "base"





    I got this:





    The view of the first camera disappeared.

    Am I missing something?
