    Seeing the same issue. Only since 2017.3, not an issue in 2017.2.

    App hangs at all on android if paused/resumed (switch app, lock phone, etc) if graphics jobs are enabled.

    Error in adb is "[EGL] Unable to acquire context: EGL_BAD_ACCESS: EGL cannot access a requested resource (for example a context is bound in another thread)."
