[Android][URP] Black background on some devices when using stacked Cameras

Unity Engine

Hey there,

Recently I’ve been having issues on certain Android devices, where the stacked cameras opaque black pixels instead of transparent ones. Most devices work normally, but it seems that the following devices have issues with Camera stacking:

  • Lenovo Tab M10
  • Moto G73

Result (on the devices listed above):

The expected result should be 3 cubes on a skybox.

Unity version is 2022.3.43f1 (also tested with the latest LTS 2023.3.51f1, same result).
URP version is 14.0.11.

Steps already tried (but didn’t work):

  • Changing the overlay camera’s clear flags to “Don’t Clear”;
  • Removed HDR and post processing from URP’s settings files;
  • Switched order or OpenGL3 and Vulkan in Player Settings;

Any help you be greatly appreciated, thank you!

Edit: This thread has a workaround for anyone with this issue!
