Replying to rblazek:
I presume that you are printing polygons.
Correct.
It is obviously impossible to print boundaries of simple feature polygons with dashed line. Because the boundaries are duplicate the gaps are overlapped by boundary of adjacent area.
OK as to simple feature polygons (though I wonder if other GIS softwares have the same problem). But the same happens with GRASS areas - dashed boundaries (not duplicated for sure) are rendered wrong. Why?
If you realy need dashed boundaries you have to use GRASS layer of boundaries (not areas) which are not duplicated.
Thanks for the hint. This works. But it is quite a hassle to have add categories to all the boundaries, add them as another layer to the project and vanish the boundaries in the area layer - just to able to print boundaries dashed. An overkill and most users will not know how to do it. And first of all - since QGIS provides a feature to render and print boundaries dashed, while it fails to do it properly, it is a bug.

QGIS is based on SF so GRASS areas are alos represented as SF. Definitely this cannot be fixed, it is NOT BUG, it is feature. Please dont reopen the ticket.

It is not a bug beceause it cannot be fixed? That's not logical.
Please dont reopen the ticket.
Sweep the dust under the carpet as you wish.
