Steps to repro:
1a. new universal rp template project
1b. add attached graph to a material, add the material to an object
2. arrange windows to see scene view, game view and inspector
3. select the material in project view
4. observe different appearance in all views (expected)
5. resize some window panes to trigger refresh

expected: appearance of material does not change in any window
actual: we see the depth sampled from the wrong window's depth texture
