/*
* Disable NGG with geometry shaders. There are a bunch of
* issues still:
* * GS primitives in pipeline statistic queries do not get
* updates. See dEQP-VK.query_pool.statistics_query.geometry_shader_primitives
* * dEQP-VK.clipping.user_defined.clip_cull_distance_dynamic_index.*geom* failures
* * Interactions with tessellation failing:
* dEQP-VK.tessellation.geometry_interaction.passthrough.tessellate_isolines_passthrough_geometry_no_change
* * General issues with the last primitive missing/corrupt:
* https://bugs.freedesktop.org/show_bug.cgi?id=111248
*
* Furthermore, XGL/AMDVLK also disables this as of 9b632ef.
