By default, Nageru uses zerocopy from the GPU to the VA-API buffers in order to
reduce memory transfer bandwidth, but this depends on EGL support (as opposed to
the older GLX standard), and also that the GPU you are rendering to also
supports VA-API. NVIDIA's proprietary drivers do not support either. Unfortunately,
