I am not sure what happens here, could you please send your code and a
screenshot that shows the problem? For me the following works fine. I
get two spheres, and the layout and the vertex sizes and edge widths
are all fine.

g <- graph.ring(20)
l1 <- layout.sphere(g) * 2 + 2
l2 <- layout.sphere(g)
rglplot(g, layout=l1, rescale=FALSE, edge.width=30, vertex.size=30)
rglplot(g, layout=l2, rescale=FALSE, edge.width=15, vertex.size=15)
