Vector 2022 body text doesn't use subpixel rendering, at least on Windows. This makes it look look less crisp / more blurry on standard DPI screens. Someone has even complained that the text is "too faded", and I think this is why: https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#Vector_2022_text_is_too_light
Many CSS properties disable it as a side-effect, including 'animation' and 'opacity' (even when there's no animation and 100% opacity – just using the property causes this). I haven't figured out what is causing it in Vector.
This is my pet peeve, and I complained about this problem before in various products: T146339 T179988 T269145#6661061 (some of those reports may have better explanations).

If you aren't familiar with this technique: subpixel rendering produces an effect on your screen that looks kind of like this, with crisper, narrower lines at the expense of some color fringing:

| New Vector |  |
(It looks better in practice than in my illustration here, I'm not sure how to accurately reproduce it.)
