Toruses are fourth-order equations, so they require numbers fairly close to
zero in order to avoid floating point innacuracies. When the camera is too
far away from them, innacuracies are introduced, and the toruses won't be
displayed properly.

If you can live with a closer camera, do that. If not, I believe someone
somewhat recently posted a patch which causes toruses to render more
accurately but more slowly (by bringing the camera closer on a per-sample
level).
