    I am having an issue while trying to run a BeginTransofmrFeedback and a EndTransformFeedback. While running on the PC with the PVR frame emulator I have no issues. This is the trace I have attached in ticket 626. However when we move over to the headunit that is running the native Power VR series 6 system we are running into opengl errors GL_INVALID_OPERATION. I have made sure that the input and output buffer are good as well as a valid program. I also have checked that the transform feedback is not active before we do the BeginTransofmrFeedback.

    We originally did this change as a tip from you to avoid 3D flushes mid-render.

    Thanks,
    Devin
