    Hey,

    We just released a new version of our game using 5.1.2p3 (previously we used an earlier version - 5.0.3).

    Using this Unity version we experience EGL errors that we haven't seen before, all with the message: "Unable to acquire context" (but with a different reason).

    For example:

    EGL_BAD_NATIVE_WINDOW
    EGL_BAD_SURFACE
    EGL_BAD_PARAMETER
    EGL_BAD_ALLOC

    None of these were experienced before this version.

    Is this a known issue ? it occurs on a range of different devices and OS versions. I have no idea what may be causing it (we could not reproduce it here during our testing).

    We did fix some of those issues in later versions of Unity. But if you know some of the devices where it breaks it would be nice to get a bugreport so we can confirm it's actually fixed.

    Unity 5.1 had a pretty massive overhaul for the graphics implementation.

    [EGL] Unable to acquire context: EGL_BAD_NATIVE_WINDOW: A NativeWindowType argument does not refer to a valid native window.

    I've started to see the following when moving to Unity 5.2.1f1.

    I've included our device and OS lists the crash has occurred on.
