Actually I suspect gl_ClipVertex is mostly ok, but you're writing garbage to it and relying on the fact that user plane clipping is disabled so the output isn't actually used. Or something like that. This is where we failed (using the clipvertex output for ordinary clipping even if user plane clipping is disabled).
