Ah, sorry, obsidian is more blurry than the same pdf opened in that viewer you linked.
I’ve screenshotted both apps in one go, and the blurriness is visible if I open the attached image itself so it’s full screen.
And while the image compression is altering the results, since the left one is clear to me ‘in-person’, you can see that the right one, which is from obsidian, is more blurry when compared side by side, especially if you look at the formulas.
