So I'm guessing this is due to an unantipicated difference in how code generation works with the Radeon back end. Arek, would it be possible to find a shader from pixmark_volplosion that compiles to worse code after the patch, and upload both the shader source and the resulting Radeon assembly code (both before and after)? That would be very helpful to me in figuring out what is going wrong. Thanks.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
