LWRP rendering is too dark on some mobile devices

    I have just upgraded to Unity 2019.1 and pleasantly discovered that LWRP is now production ready (I am using 5.13.0). After upgrading our test project I was shocked by the massive speed improvement on some Android devices. Two thumbs up!

    However...
    There is a big difference in the lighting on some Android devices. Here is a scene rendered correctly on Samsung Tab A 10.5:
    samsung_tab_a_10_5.jpg
    And the same scene on Pixel 3 which is way too dark:
    pixel3.png

    As you can see the UI elements are rendered correctly (button, properties at the bottom), while everything which is 3D rendered was just not lit properly. There is only one directional light in the scene which is slightly rotated, plus ambient lighting is set to color (#B4B4B4).
    There are no post-processing effects set up.

    Any idea why does this happen?

    Hi!
    A fix is coming soon :)
    I'll drop a line when it's there.

    I can confirm that this issue has been fixed.
    There are new issues now, but that is a different question. :)

    @aleksandrk i have the same issue on IOS 12.4.1 and Unity 2019.2.0f1 - is it fixed in 2019.2.x?
    Same question - what can i do to make it go away?
    It does not seems to be present in other projects or scenes?

    @Flindt iOS does things very differently, so it's a different bug, I guess. Can you please submit a bug report?

    @aleksandrk - I am on Unity 2019.2.14f1, LWPR with standard post processing stack and I have experienced the very same issue as described above on Android devices. Does it mean the issue has regressed?

    @angel1st no, it's still not fixed on 2019.2.

    @aleksandrk - Any planned timeframe on that? Or at least can I have a link to the issue, so I can monitor and see when / if it will be fixed?

    Correct for the link, I assume the time for fix is not estimated?

    That's correct.
    I will take a look soon, though :)

    @almosr, @aleksandrk - while waiting for the fix, what would be possible workaround solution, applicable for 2019.2? Apart from the most obvious one to disable post processing?
