@Hildo: I do not believe this has to do with the PDF rendering.
1. I am using the Adobe Acrobat Reader DC, I think that it is the reference;
2. I get the same behavior with SVG in Inkscape, Google Chrome and Microsoft Edge.
Two different outputs (PDF and SVG), and different tools with the same rendering: 99.9% probability that it is the KiCAD generator.
