Right, I remember about it as well. Once a few morphs are added it get really slower pretty quickly.
The discussion you refer is there: http://forum.world.st/Redraw-suggestion-for-Athens-tt4750951.html#a4751188 Regarding DrGeo canvas, it does not really need and rely on the change mechanisme of Morph: model tree is updated in one shot, then the views are updated in one shot after. But may be there are leftover change in the used view, not necessary to drgeo but implying unecessary update.
