MobileGestalt no access to InverseDeviceID

Question

This happens with every app when I try to use OpenGLES on my iPhone7+ with iOS10.3. But it works without any problems on my iPho

Answer 1

I had the same issue. It turns out to be multiple thread accessing the same OpenGLES related resource, EAGLContext to be specific. I guess it is possible that OpenGLES related codes are not thread-safe, and it behaves differently in different OS versions / iPhone 7 / 7+, sometimes it messes up the memory.

After making sure data accesses are synchronised across threads, the problem is gone.
