The spec for GL_EXT_disjoint_timer_query says > The GetInteger64vEXT command is required only if OpenGL ES 3.0 or later > is not supported. Some GLES 3.2 implementations like the proprietary mali driver on the rk3566 based OrangePi advertise GL_EXT_disjoint_timer_query but lack glGetInteger64vEXT. Use glGetInteger64v instead.
