Neon Visual Glitch with One Staff Line

Since I'm working with Aquitanian notation with one staff line, I've been trying to use Neon for visualizing MEI outputs. However, it seems when I have a file where @staffDef `lines=1`, there's a pretty bad visual glitch that covers the whole page. This seems to occur both in Rodan's Neon and the standalone DDMAL Neon.

Here's what it looks like with `lines=1`:

Same folio with `lines=4`:
