But those coords came from the vs, which seemed simple enough. So possibly the NaNs might have been the result of a previous render pass. (It is of course also possible some shader is simply bogus and relying on NaNs getting flushed to zero somewhere on output.) It would indeed be helpful to know if hw drivers are affected too. (Using vtk sources to reproduce is pretty easy.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
