What's weird about this one is that the bottom part of the planet's "rings" disappears when drawn at the higher resolution of 1600x1200, instead of being drawn sharper!

You are probably using passes=g. What's happening is that the first coarse pass is probably missing the thin line and assuming that nothing is there on the subsequent passes. Try rendering the image with passes=t, or if that fails, passes=1.
The lower "rings" come into view only with 640x480 and 1280x1024 if passes=1. At 800x600, 1024x768 and 1600x1200 they disappear. But at 1280x1024, they go all the way to the bottom of the screen - but, like you say, changing to passes=g will also cause them disappear. Apparently the line is so narrow, that some of the resolutions miss it entirely, even at passes=1.
