Adding a background image that is not affected by the Default Rendering Pipeline post processes

@Evgeni_Popov @sebavan

Hey folks,

I ran into an issue when I use: forceAutoClearInAlphaMode.

I am doing similar thing like this PG (this is from another thread)

After I evoke forceAutoClearInAlphaMode in my own code, I do see the all the post textures get cleared. However, the yellow background is also disappeared. The listed PG doesnt have that artifacts but in my own code base I encountered it…I couldnt replicate the issue in a PG but I do observe the problem…

Any clue for this issue?
Many thanks,
