    I have the same problem but on the iPad 4 with Unity 5.3.5 and 5.2.4.
    In my project a 3D model does not render as expected and I have a problem with the viewport rectangle of the camera (I think it is the viewport) because the entire gui is stretched in one part of the screen (the gui is made with an external framework)

    Further testings shows it occuring in Unity 5.3.5p2.

    When the text is changed in the UI Text component, Xcode immediately reports:

    OpenGLES error 0x0502 in /../Classes/Unity/GlesHelper.mm:339

    Running on iPad Air 2 (iOS 6.2.1)

    Would also add that it appears on build using just OpenGLES2 and also in a build using both OpenGLES2 and 3.

    Also seen in Unity 5.3.5f1.

    OpenGLES error 0x0502 ...../Classes/Unity/GlesHelper.mm:339

    When reported in Xcode log, can see missing letters and numbers from text using standard GUI/TextShader with dynamic .otf font.

    Appears on iPad Air 2 but not (yet) seen on iPhone 6.

    Same issue here on 5.3.4p1, iPhone 5, using Mobile/Vertexlit. Blocke since this issue seems to kill the framerate!
