Yeah, font bugs like this are frustrating. Both JavaFX[1] and the JDK[2] 
had the same problem on Linux for years. It can be an uphill battle to 
get them fixed, especially when they concern anti-aliasing, hinting, or 
sub-pixel rendering. I found one very effective trick: magnify by eight! 
I think that should be a requirement for any font bug reports.

I want to fix this bug, but that shouldn't stop anyone else from fixing 
it first. I just haven't gotten around to it yet, and I never debugged 
Java or native code on macOS before, so I have a lot to learn.

Those earlier font fixes taught me that if you can write and debug Java 
application code, you can write and debug code in JavaFX and the JDK, 
too. So you might consider trying to fix it yourself. When successful, 
it's like gaining a superpower. ��
