6297	Graphics is computing mesh edges for surface twice	Tom Goddard	Tom Goddard	"The graphics code computes the mesh edges for a triangulated surface twice when displaying mesh style.  That mesh edge calculation is very slow as noted in ticket #6279, three times slower than computing the volume contour surface which is then shown as mesh.  The extra edge calculation is for the selection highlight but occurs even if there is no selection.

Would be good to optimize this so only one calculation of mesh edges is done, since it slows down ISOLDE considerably updating x-ray maps for new phases several times per second as described in #5964."	enhancement	closed	moderate		Graphics		fixed		Tristan Croll				all	ChimeraX
