    Sometimes when I want to test a new build on my Galaxy S5 (Android 5.0.1) the screen turns black / dark grey and flickers. The splash screen is not shown. When I press the Android Home button and return to the app the screen is all pink and the flickering has stoppped.
    Then when I kill the app and start it again it works fine.

    Has anyone else seen these issues?

    My app is forced to use OpenGLES 2.0
    I am using Unity 5.2.1p2

    Bug: case 736369

    I have same problem in the version 5.2.1p3
    it was resolved by loading the game scene after the empty scene.

    I also have this log in one confirmed instance where we encountered graphical glitching followed by pink textures on some of our ui. Seeing this very rarely on android only, so far our occurrences seem to be after install on the first app run. Requires the app to be killed to get rid of it, as you mentioned.

    Unity: 5.2.0p1
    Devices:
    Nexus 6, os 5.1 (confirmed gsls link fail log below)
    Nexus 4, os 4.3 (no log)
    Galaxy S5, os 5.0 (no log)

    Our first reported instance of this issue coincides with our upgrade from 5.1.2p2 -> 5.2.0p1, for what thats worth.

    It's happened to me here too (Unity 5.3.5f1)... So it's not fixed at all, is there a way to reopen a bug ?

    Same thing just happened to me. Can we get someone from Unity to comment on this?

    My app crashes on startup with "GLSL link failed, no info log provided"
    When I run it for the second time, everything works but this is annoying.

    We're also getting this error when launching our Underground version downloaded from the Amazon Store because they force a popup at the very beginning. I guess this pauses Unity and makes a bunch of GLSL link failed errors.

    Because of this, our player character doesn't appear in the levels. You can play but he is never rendered. Not even in the character select ... I hope this gets fixed but I have to figure out a way around it.

    We also have the same issue with our app. We have many exceptions thrown in our google analytic with this error.
    -------- GLSL link failed, no info log provided.
    Only on android. Did someone found a reason/fix/information about this?
    Almost all Android devices and firmware seem to be impacted..

    This thread is quite old but I think our users are experiencing the same issue on Android. We're using Unity 2019.2.18f1. We haven't been able to reproduce it ourselves so we have no clue how to fix it :( Doesn't anyone have any suggestions?

    Which graphics API you are using? I've seen similar issue with some Android GPU drivers, they did not like rendering to render texture with 8xMSAA + without depth buffer and would crash after flickering for couple of seconds. Fix for that issue is in Unity 2019.3

    @rjonaitis We're using OpenGLES3 only. We're also using LWRP 6.9.1. Our game has MSAA disabled in the LWRP.

    Moving to Unity 2019.3 makes me very nervous considering it just came out of beta, I was hoping to give it a couple of months to stabilize before jumping in.

    All the devices experiencing the problem so far are Android 6.0 and 7.0

    There's nothing more I can do without a reproduction project, as this seems like a specific drivers issue since you were unable to reproduce it yourself.
