(The fast clear rectangle looks fine - just the resolve is wrong.) See 3D > Pixel > Pixel Backend [IVB+] > Render Target Resolve [IVB+]. The attached patch tries to work around it. With that patch, EgyptHD performance goes up by 2.75x to the expected speed (the one I see when using repdata clears only). Unfortunately, I'm not physically in the same location as my Broadwell machine's monitor right now, so I can't watch and see if the rendering is correct or not. But it does pass Piglit.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
