I think Google is already doing the right thing. From the ES GLSL spec: "When no interpolation qualifier is present, smooth interpolation is used." So there should be no problem having smooth in one stage and nothing in the next as the default is smooth. I looked at this problem last year after seeing issues in other deqp tests and had a fix but I wasn't sure at the time the impact on desktop GL. Looking at it again it seems its always smooth by default too unless there is some compat builtin stuff going on but that shouldn't be an issue. I've sent a patch for this half of the issue to the mailing list. <a href="https://lists.freedesktop.org/archives/mesa-dev/2016-February/107692.html">https://lists.freedesktop.org/archives/mesa-dev/2016-February/107692.html</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
