Reproducible with: 6000.0.30f1, 6000.0.57f1, 6000.2.4f1, 6000.3.0b1
Not reproducible with: 6000.0.29f1

Reproducible on: Windows 11

Notes:

• Issue reproduces when one of the Cameras is set as Overlay and stacked on the Main Camera and in the Renderer asset has a different asset set. Does not reproduce if both Cameras have the same Renderer selected
• To test in 6000.3, you must add URP_COMPATIBILITY_MODE in Scripting Define Symbols (Edit > Project Settings > Player)
