Resolution Note:
Won't fix: render texture specifies depth buffer format D32S8, which is not supported by the device. Render texture creation fails and the camera renders to backbuffer instead, then ReadPixels retrieve data from backbuffer instead of render texture. Backbuffer and RenderTexture differ in Y direction flip.
Workaround: specify render texture with lower depth buffer precision, D24S8 works as expected.
