    Depth priming + MSAA doesn't work on GLES. There is a PR in progress that disables it on GLES when MSAA is enabled.

    As a general advice using depth priming + MSAA at all on mobile is VERY expensive and it is not providing any benefit, since most mobiles have hardware HSR so depth priming would give you no performance gains anyway. So using it on those platforms is not recommended.

    We are adding an extra option to force a depth prepass (but not using depth priming) if that is what you need
