I noticed that if you write gl_BackColor but not gl_FrontColor, the value that lands in gl_Color in the fragment shader is junk; same for the corresponding secondary color builtins. This causes us to fail 12 of the interpolation piglits.
There's a series from July of last year which was supposed to fix this: http://lists.freedesktop.org/archives/mesa-dev/2012-July/024117.html ... but it looks like it went nowhere. What's the current thinking on this? I'm happy to do the work if there's some consensus. -- Chris _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
