This works for me on Ivybridge (using Mesa master from today). The artifacts in the screenshot look kind of like the noise you'd get without the Gen4 SEND dependency workaround...or a 16-wide-texturing-on-8-wide-shaders bug. But if this was Mesa master, those should be working. I'll have to check when I'm home and have access to a GM45. Unless someone else beats me to it, of course... Sorry for not getting to this, still... However, Chris just fixed a bug with a screenshot that looks extremely similar: Screenshot of that bug: https://f.cloud.github.com/assets/5004176/793321/2a7e37f8-ebf7-11e2-8361-536741cb4417.png Patch: http://lists.freedesktop.org/archives/mesa-dev/2013-July/041749.html The same code applies to original Gen4, so I bet it fixes this too. Scratch the comment about original Gen4, I forgot you *are* on GM45. So it's almost certainly that same bug... This patch does indeed fix the broken rendering in that trace. I'll reference this bug number when committing the fix. Fix is in master now. |
