JOVR with JOGL and SDK rendering

If you follow the standard rendering loop (just compare with this) then everything should work fine. There is probably just a minor bug in your code. What may happen is that some OpenGL related state is set in a way to cause trouble with the SDK. For instance, play around with unbinding all your framebuffer/textures/VAO etc. You may want to check the GL error state at various places in your rendering loop to see if any the the SDK calls fails (for some reason in my code the hmd.endFrame always fails just for the very first frame I render, but in general you should not see a GL error after calling an SDK function).
