"Trying to load color backbuffer into a complex RenderPass setup" error is thrown after entering Play mode in AR Mobile template project

Unity: SRP Foundation

Linux

Fixed

6.2.X

6.1.X

6.0.X

6000.0.23f1 onwards

Unity graphics engine was using a wrong check to determine whether an attachment is a back buffer or not when using Render Passes. It has been fixed and URP (using Render Graph and Render Passes in Unity 6) doesn't throw this error anymore. Thanks for reporting this issue.

Steps to reproduce:

1. Create a new project using AR Mobile template
2. Enter Play mode
3. Observe the Console

Actual results: "DrawTransparentObjects: Trying to load color backbuffer into a complex RenderPass setup, results undefined.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)" error is thrown
Expected results: No errors or warnings are thrown

Reproducible with versions: 6000.0.23f1, 6000.0.29f1, 6000.1.0a6
Not reproducible with versions: 2021.3.45f1, 2022.3.53f1, 6000.0.22f1

Tested on (OS): Ubuntu 22.04

Notes:

Not reproduced on macOS Sequoia 15.1 (Intel)
