Step to repro:
- Import attached package
- Open Scene "Repro_PostProcess"
- Select Repro_Parent Material, switch the rendering pass to "After Post Process"
- Both object are now colored
- Click on Repro_Child to display it in inspector
- The Sphere switch to black & white
Expected:
No automatic update only displaying inspector
N.B.: The root cause issue is actually sync of renderqueue only done in GUI
