Related question: is what’s happening here similar to how on old Apple computers, if you look closely at white text, you can clearly see green and purple pixels within it?
No - that was because of composite artifact colors, this is because of ClearType.
Nope. Apple used its own sub pixel rendering approach - that wasn’t ClearType. Apple emphasised fidelity of letter spacing - for layout designers - which made fonts at small size famously ‘soft’ or fuzzy. I rather liked the effect, others didn’t.
They nuked in in MacOS Mojave with the rise of Retina displays
