Hi Alex,
>I just hoped we could make vanilla laod the same fonts in all platforms and that patches would all look the same as in Purr Data, what's preventing it from happening?
To put it fast and dirty but not incorrect:
Purr Data uses web-browser technology to do the GUI. Basically a Chrome browser. That’s why you see that fonts are rendered the same across Oss.
Then I kept testing, did check Pd-Extended, which I think didn't have any similar issues
