I was making a logo from multiple shapes... and came up with a lot of garbage on the stage. I thought may be it happens so I tested other software.. Xara there everything was quite smooth with nothing extra on stage.
To do this..
create multiple circular shapes or only circles randomly positioned overlapping each other.
Select them all
add vector color+some visible thickness
Hit "Divide"
now start moving shapes apart..
you will see a number of leftover garbage stuff on stage.
Please take a look on video to understand it more clearly what I mean.
