[Bioperl-l] Can protein glyph tracks interfere with other tracks?

[Nathan Liles]

I'm trying to patch Gbrowse to properly display circular segments. 
Currently, I'm working on getting the protein glyphs to display properly 
beyond the end of the track.

I noticed when I turn on the protein track, it can sometimes affect 
another track. Specifically, turning on the protein track can either 
cause the gene glyphs to disappear or be duplicated.
This only happens for features with two subfeatures that appear on the 
panel at opposite ends.

This seems strange since I can't imagine how one track could affect 
another.
Has anyone noticed this behavior before?
Can anybody think of a way that the protein glyph module can affect 
other glyphs?

Thanks,
Nathan Liles
