I need a footprint with plated slots and found this rather strange behaviour in Altium designer 19.1 (no, i dont want / can upgrade): When the slot is set as "Slot" the polygons have a big clearance, but if I use "Rect" they behave as expected.
It is also strange that the pads seem to be bigger internaly (see the transparent selection marker)
Is this a Bug or intentional?
