On a rendered surface I will often superimpose the mesh (showgrid) in white with a small opacity value (with a unit value the mesh is too visually detracting from the data-colored surface). The works great with software rendering, but with hardware rendering the mesh is not shown at all with an opacity value less than 1. Is this another case of a shortcoming in hardware OpenGL rendering?
