[iOS] Changing the screen orientation via a script sometimes results in corrupted view on iOS 10



When the orientation of the screen is changed via a script (with Screen.orientation) on iOS 10 devices, sometimes the screen remains in portrait orientation, but the game view gets flipped and goes over the edge of the screen and leaves black area in the bottom part of the screen.

Steps to reproduce:
1) Open the attached project.
2) Build 'MainScene' for iOS.
3) Run on an iOS 10 device.
4) Press the 'Switch to landscape' UI button.

If the button is clicked 2-3 seconds after launch - the rotation should fail - black area appears at the bottom of the screen, half of the game view is not visible. If it does not, quit the app completely, re-launch it and repeat step 5). This occurs with both Metal and OpenGLES on iOS 10.

Reproduced on:
5.5.0b5, 5.4.1p3, 5.3.6p6

    Please change the Category "iOS" if you can because it happens in Android too with Unity 5.5 versions too.

    Its not in all devices but for example in Lg9 or Samsung Galaxy Mini it happens exactly the same, and I'm sure that are more devices with the same problem.

    I tested with 5.4 with an empty project and there it works well, but if I move the same project to 5.5 (or 5.6 beta) the problem persists.

    I tried DARKMAGICCK's workaround and many others but none of them works. If I change the app and back to it, the problem solves, but that's not an available option.

    And my problem dosen't end here, I've been working with the 5.5 for a long time with that project, and if I try to move it into 5.4 version, it crashes everywhere because of "new serialization version for GameObjects" of 5.5 is Not compatible with previous versions. (More info here:

    So, now I have a game that you can not play and obviously I can not upload to Google Play nor Apple Store, and I can not do anything about it.

    So please Unity, fix it as soon as you can.

    In Android happens the same in a lot of devices. This is a major bug, why take so long to be fixed?

    I don't understand how come this bug is not fixed yet!
    Please do something about it Unity.

    I used ETHAN_VISUALVOCAL's way to deal with this issue and I want to thank him but it still is a temporal fix.

    Unity team, please fix this issue, I'm waiting for this several months now.

    Come on Unity, please fix this asap, or at least reply here if there is going to be an even bigger delay.

    This kind of crash may happens if you have set a Application.targetFrameRate = 60 for iOS.
    Try to remove it and then it won't crash when coming back to app after lock button.
    Doesn't affect the home button.

    Any news on this? Could not find a workaround that did the trick so far and the bug is a huge problem for some apps.
