Bug Description

Hello,

I am using KiCad 6.0.0-rc1-dev-105-g28a5253 (although I have had the problem in previous 5.0.0 nightlies too) on MacOS.

I have a capacitor with rounded rectangle pads connected to VDD and GND, put inside a VDD zone. The zone has the same Clearance and Thermal clearance (both 6 mils), however when rendering the zone, the clearance behaves differently for the two pads.

The GND pad (the one not connected to the zone) has its clearance computed correctly, while the VDD pad clearance seems to behave as if the pad was a Rectangle instead of a Rounded rectangle (see the screenshot attached).
