Hello, I compared latest ConTeXt standalone (LuaTeX 2.08) against TeX Live 2020 (LuaTeX 1.12). The produced PDFs are: https://miletic.net/lipsum-112.pdf https://miletic.net/lipsum-208.pdf Viewing them with Evince (and I assume Adobe Reader, I don't have it at hand to test) shows only minor differences in (horizontal) character spacing, which I would expect; the text looks reasonably good either way. However, viewing them with PDF.js shows a large difference: https://miletic.net/lipsum-pdfjs-112.png https://miletic.net/lipsum-pdfjs-208.png As you can observe, b, m, n, p, and r (and possibly others) are moved slightly above other letters. Is this the expected behavior? If not, is this an issue with the way PDF.js is displaying the PDF or the way LuaTeX is producing it? Thanks in advance.
