Overlay camera doesn't work on Vulkan 1.1.0 (L0) android devices

I am using overlay camera for rendering UI on top of my main camera. The project uses URP, and the pipeline is up to date. On most of the phones it works fine, but on devices with Vulkan 1.1.0 (L0) UI camera renders everything besides UI is completely black. Unity version is 2021.3.44f (tried it on 2021.3.14f as well) it is reproducible on any device with Vulkan 1.1.0 (L0). Oppo Reno 3 was my test device. I completely redid the workaround the UI but this issue should be addressed. Tried many different settings and creating different URP assets test it with all. Only solution is to not use overlay camera.

Maybe try the latest version of 2021. If that doesn’t work 2022 also might be worth a shot.

Also please share how it looks and how it’s setup

To be honest upgrading to 2022 is not worth the effort right now, I tried it on latest 2021.3.45f with creating a new project using main camera as base, a second camera set to overlay (listed on main camera overlay list), adding texts on ui. Same problem exist on Vulkan 1.1.0 (L0) android device. It effects like 3-4% of the average US android devices.

Then file a bug report. But I am not sure if any bugs for 2021 will get fixed, hence why I suggested to move to 2022. If it’s an issue here and Unity reproduces, you will get a fix for it
