<pre>The multimedia presenter info-beamer ( <a href="http://info-beamer.org/">http://info-beamer.org/</a> ) just renders a
black screen with r600g.
It's working fine with software rendering and on Intel hardware.
Not a regression, or at least present in Mesa 9.2.
I've made an apitrace of one of the beamer demos:
<a href="https://my.owndrive.com/public.php?service=files&t=cef11b335be2741058363783176b14cd">https://my.owndrive.com/public.php?service=files&t=cef11b335be2741058363783176b14cd</a>
The trace renders correctly but gives a lot of errors, so this might be a bug
in info-beamer:
0 87813 glGetUniformLocation(program = 0, name = "Color") = -1
87813: warning: glGetError(glGetUniformLocation) = GL_INVALID_VALUE
