Mmm... we got rid of the noise but the back face should be color-interpolated so there is still something wrong. I'd need to narrow the problem down to some of the features we are using here: Could you try the following? 1. Disable AA only: Remove glEnable(GL_LINE_SMOOTH) 2. Disable blending only: remove glEnable(GL_BLEND) 3. Disable AA and blending 4. Do 1-3 again but removing also glPolygonMode(GL_FRONT, GL_LINE) In the meantime, considering that the original code back in the day used JMPI to implement this in gm45 I'll try to cook a patch that uses this. It did not work for me in ironlake, but maybe it does for gm45, otherwise I guess it might have always been broken like this. > PS: > I didn't pay attention to it last time, but color interpolation is broken > for the lines(front face) too, independent of your patch.

Yes, that happens in ironlake too, but as you say this was independent from the patch and is a different problem.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
