The Legacy3D FALSE option may help you bring the GEM environment up in a
limited-aperture-space situation.

On our end, we should also cut back the EXA offscreen space in the
presence of limited aperture to increase the chance of success.  Also,
we could use Legacy3D as a signal that it's safe to resize the
framebuffer, and actually do that.
