Am I missing something? Taking a wild stab in the dark, I'm going to guess that you're hitting an ARB or fixed-function program. Those come in via the prog_to_nir path and the uniform setup is a bit different.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
