Hi all.

I’ve posted a thread about this issue in CD12, but would just like to know if the same problem arises under CD11.

First create a number of overlapping objects, give them a dark fill, select all, and then remove their outline colour, by right clicking the no colour swatch.
Now, if you click Simplify, do the shapes show a white line around the areas that butt up against one another?
