screenshot from Okular
I guess it's the poppler bug with Type 3 bitmap fonts. https://gitlab.freedesktop.org/poppler/poppler/-/issues/981 The fonts look bad (or even worse) in Chromium/Chrome embedded reader as well. These fonts are never intended to be used for reading from a screen. Please install cm-super package and regenerate the PDF with the modern LaTeX or print (as intended) then read it. okular doesn't do any pdf rendering, so not okular's fault. |
