Interesting. I have not been able to replicate this issue on Mac. Here is the default font stack:
-apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,Oxygen-Sans,Ubuntu,Cantarell,"Helvetica Neue",sans-serif;
This code tries to use the default system font across OSs. It would be interesting to see if you can identify which font is causing the problem by removing fonts one at a time from this list (in the custom font settings of Minimal)
