392	"""round"" ribbon (cartoon) normals may be wrong"	Elaine Meng	Conrad Huang	Maybe there's a bug making the ribbons look too fat and bulgy, see attached image showing a comparison between Chimera and ChimeraX ribbons with same width and thickness.  I suspected the normals because we had the same problem in Chimera for years.  Tom Goddard said:  in Chimera 1 the issue was that the ellipse ribbon cross-section was using normal vectors that were appropriate for a circle — the ribbon thickness scaling wasn’t adjusting the normal vectors.	defect	closed	major		Depiction		fixed						all	ChimeraX
