Mmm .. it can't be the same bug even if the effect is similar.
We don't use freetype on macOS, that's for Linux.

Can you check your display's settings ?

I have a Dell U2412M and it has a menu similar to what he sees and macOS 
for me defaults to RGB,
and selecting YPbYr results in a LOT more problems than text because I 
don't think macOS is
changing the signal when I do - I am connected via displayport too FWIW 
but have an old mac (2015)
and an old OS (10.13.6),

BTW I found the incident (bug report) and I see it is submitted as an FX 
regression
in 14.0.1 when I haven't seen any reason to suggest this is the case.
Isn't everyone seeing it just when they move to catalina ?

Can anyone say if they definitely see it on a built-in retina display too ?

You might also want to check what color profile is set in System 
settings -> Display -> Color.
