Command buffer attached to the main camera, creates a temporary render target from a texture array in the provided shader.
The first pass renders a flat color, from green to yellow, to each of the texture array slices. The second pass renders them adding a constant blue color, the last one should be white (yellow + blue), but that is not happening.

Repro steps:
1. Open my attached project.
2. Play TexArrays scene.
Notice that color rendered to screen is blue.

Expected result: screen is white
Actual result: screen is blue
