This is the mwe of the problem I have in Beamer. If I only use the "english" option in babel, everything is fine, if I add "russian", the text becomes bold. It only seems to occur with /tiny text This is an unwanted outcome. How to get rid of it?

\documentclass[10pt]{beamer}

\usepackage[utf8]{inputenc}
%\usepackage[english]{babel}
\usepackage[english,russian]{babel}


\begin{document}
\tiny bold text?
\end{document}

    It seems that this is a bug in cm-super font collection. It provides all fonts from optical size 5pt. Original CM fonts provides sans serif from 8pt, so sfss0500 (from cm-super) is generated by a specific way and it is generated badly. You can look by fontforge that the font sfss0500.pfb is bad. And \tiny in LaTeX selects the font at this small size. When you don't select russian in babel then cm-super font collection is not used. – wipet Mar 26 '23 at 16:50
  • @wondering Do you need to use computer modern font? Would using another font be an option? – samcarter_is_at_topanswers.xyz Mar 26 '23 at 17:29
  • @samcarter_is_at_topanswers.xyz Yes, using another font would be an option. How would the solution look like? – wondering Mar 26 '23 at 18:52
  • You could try e.g. \usepackage[default]{opensans} if you like to stick with pdflatex or see https://tex.stackexchange.com/questions/114587/what-fonts-are-compatible-with-t2a-cyrillic-encoding for more options. If switching to xelatex or lualatex, you have more options. – samcarter_is_at_topanswers.xyz Mar 26 '23 at 19:00
  • @samcarter_is_at_topanswers.xyz Thank you, this is a solution. – wondering Mar 27 '23 at 07:45

If you are not set on using using computer modern font, you could switch to some other font, e.g.

\documentclass[10pt]{beamer}

\usepackage[utf8]{inputenc}
\usepackage[T2A]{fontenc}
%\usepackage[english]{babel}
\usepackage[english,russian]{babel}


\usepackage[default]{opensans}


\begin{document}
\begin{frame}
\tiny bold text?


Видимое свечение чистых жидкостей под действием $\gamma$-радиации
\end{frame}
\end{document}

(see What fonts are compatible with T2A (Cyrillic) encoding? for more fonts which support Cyrillic)

  • As the problem seem to be caused by a bug, I guess this solution can be accepted as an answer, or what is the policy? Also I wonder if one could somehow just "unbold" the text by e.g. the \normalfont command. I seems not to work, though. – wondering Mar 27 '23 at 19:10
