On the pic, the left window is software rendering(normal), and the right
one is direct rendering.
Comment 3 Gordon Jin 2008-12-10 05:18:23 UTC
The case is under mesa/progs/glsl/
Comment 4 Ian Romanick 2008-12-16 17:10:40 UTC
This test seems to fail because the ARL instruction is not implemented.  This isn't too surprising since this instruction is not part of ARB_fragment_program.  I tried hacking up an implementation, but the test still failed.  I don't really understand the difference between vertex shaders and fragment shaders on 965 hardware.

This issue still eixsts with current build.
Comment 6 Eric Anholt 2009-05-06 12:55:19 UTC
Works fine on master and 7.4 branch.
