Is "that's" a typo?

This comment doesn't apply to all drivers, not even all Intel drivers,
so please qualify the comment.

I applied your series on top of master and tested it on Sandybridge with
`depthstencil-render-miplevels 1024 d=z24`. The window doesn't do the app
says: "Colors should proceed  from nearly-black to nearly-red". Is that

With PIGLIT_PLATFORM=x11_egl, the window is a solid dark red. With PIGLIT_PLATFORM=glx,
the window content is garbage; it seems that swapbuffers doesn't happen (likely a bug
in Piglit).
