A second "base" Camera shows a black background when MSAA is enabled in a URP project

--

-

How to reproduce:
1. Open the “CameraBug.zip“ project
2. Open the “SampleScene“
3. Open the Game view
4. Select the “Assets/Settings/UniversalRP-LowQuality.asset” in the Project tab
5. Change the “Anti Aliasing“ to “2x” in the Inspector
6. Observe the Game view

Expected result: The background is transparent
Actual result: The background is black

Reproducible in: 2021.3.40f1, 2022.3.37f1, 6000.0.10f1

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

Notes:
- Similarly, to reproduce you can change the “Anti-aliasing” mode to “SMAA“ for any Camera (only reproducible in 2021.3.40f1)
- Not reproducible in an HD RP project

  1. Resolution Note:

    Uninitialised background in the camera means that you cannot rely on the data here. This can be anything and would likely change along the operation performed. You never can assume what would be the content.

    To properly rely on a previous camera rendering, please use the Camera Stacking. Alternately you can also use intermediate RenderTexture.
