As of commit 0486d503209cf375ae77456336742774b12eda02, my app stopped drawing triangles and displayed only a blank image. Bisection led to the commit given, and reverting just that commit has fixed the issue. I'm assuming the error is uniforms are no longer being passed correctly, so textures have gone missing. apitrace attached.
Attachment seems to have failed. I'll try to get it on when I'm on a better internet connection.

http://sadmac.fedorapeople.org/mesa-repro.trace There we go.
(In reply to comment #3) > http://sadmac.fedorapeople.org/mesa-repro.trace I cannot reproduce your symptom of blank rendering when I replay this trace on Ivy Bridge with mesa master (f6beb4c). I see a purple background, a plane, and a person rendered when I replay the trace. I also reverted 0486d503, and I was unable to see a difference in rendering. I also tried both 0486d503 and 0486d503^, and saw no difference as well. Which mesa version were you using when you tried the revert? What does glxinfo|grep "OpenGL version" report for you? -Jordan
I last tried on top of commit 7e17e72cb716c56264d4778684f6f23de69a56a1 [sadmac@baudrillard mesa (test)]$ glxinfo | grep "OpenGL version" OpenGL version string: 3.0 Mesa 9.2.0 (git-9ef2c8d) git-93f2c8d refers to my private commit to revert the change in question.
It also renders for me on my IVB.
Could this be some hardware difference between what Casey has and what Eric / Jordan has? Casey: What does "lspci -n | grep 0300" say?
00:02.0 0300: 8086:0166 (rev 09) Sorry for the delay. Email must have gotten eaten. This still showed up on Fedora 19's mesa after upgrade.
(In reply to comment #8) > 00:02.0 0300: 8086:0166 (rev 09) IVB GT2 Mobile. The apitrace renders properly for me on a Haswell.
> 00:02.0 0300: 8086:0166 (rev 09) I have exactly the same output on my IVB, I've tested with Mesa master (ce4d3f3) and everything works fine (no blank image).
