I have been using TinyTeX for my markdown documents for a while, and I think it is a great package, especially for whose who do not want a whole TeX installation in their system. I had some other problem before, and had to reinstall TinyTeX because somethings had changed in one of the updates.
This time I have spent a whole day trying to fix it. It was working, and then a moment later not working.
I really have no idea what is going on here.
Can you explain why you think tinytex package as a bug here ? Have you found some details so that we can fix if necessary.
Because just after I uninstalled TinyTeX, it worked again.
I am not sure to see where it could be inside tinytex. One of the thing the tinytex R
is doing is providing a way to install a lightweight distribution based on TeX Live. (see https://yihui.org/tinytex/). It can work with another distribution too because the other thing it does is calling Latex from R when you render a Rmd document.
This makes sense to me. But how are we going to explain the problem then? I have not changed anything else. Note that my TeXlive installation was not new. I mean, I installed it weeks before I had the issue. It was already installed on my system. So, I have not changed my TeXlive distribution either.
With your example, I get some bullet point showing if I remove the theme Madrid. The only difference in the .tex file is the line \usetheme[]{Madrid}: With this line, no bullet is shown, without this line there is some bullets showing. Could this be related to the theme and some versions of one of the tex package ?
As I said, the only change I made is to remove tinyTeX and go with (already installed) TeXlive. Are you suggesting that TinyTeX is using a different TeXlive version? Because the installed version was TeXlive 2020 with all the updates, since I use it for other pure LaTeX documents.
Also, if I switch to pdflatex engine instead of xelatex, I got the bullet. i.e using this:
beamer_presentation:
theme: Madrid
latex_engine: pdflatex
You are right. It prints bullet points when I switch to pdflatex. XeLaTeX compiling might be the source of the problem.
Which version of TeXLive did you install ? The one installed using TinyTeX is this one
TeXlive 2020.
I just want to say that between when TinyTeX was working and when stopped working, I have not touched my TeXlive installation in any way.
I also want to thank you for your inquiry of the issue.
