I am using Kicad 5.1.12
with the RF tool addon
The problem which I encountered is when I work with the Taper design and connect it to PCB lines it creates discontinuities that can not be seen in the Kicad itself (main window board and 3d Design see Pic), but only when the Gerber is generated. Also when I try to connect to those PCB lines, on the connection side of things I can see bulges (which look like a round track which is not good for RF me).
Is that the bug of the Kicad or is that issue of the additional package software?
