No, that's expected, sorry.  This patch fixed it for me on Broadwell
(which is why I noted it here), but Skylake was still broken due to a
BLORP bug.  Topi has a fix here:

I decided to push the series anyway, since stencil texturing was broken
without it, and it's required as part of ES 3.1.  Plus having all the
patches in master made it a bit easier to coordinate with other
developers.

After Topi's fix lands I think we should be all good again.
