--- Comment #35 from Samuel Iglesias <siglesias at igalia.com> ---
I found i965 driver is currently running vec4 visitor and generator for
geometry shaders and we have some crashed/failed tests due to its lack of
support for doubles. After enabling scalar GS, piglit shows no regressions.

I would like to know if there is a strong reason to disable scalar GS by
default (perhaps I am missing something) because then we would need to add
support for doubles in vec4.
