Brian,
I think this patch is wrong - shouldn't it say:
! if (!mesa_vp->Base.String) {
! /* Spec says GL_PROGRAM_UNDER_NATIVE_LIMITS_ARB is only zero if the
! * program (if it exists) exceeds hw limits.
! */
! vp->native = GL_TRUE;
return GL_TRUE; /* <<<< HERE */
+ }
The bottom line is that my Xorg server locks up if I apply your patch and run
$ WoW.exe -opengl
but works OK if r200_translate_vertex_program() returns GL_TRUE if
mesa_vp->Base.String is NULL.
Cheers,
Chris
