Run LaTeX here

there is the following problem: the first bracket after the "g" overlaps the following "f".

When I use the same code with article class like this:

Code: Select all

there's no such problem.

Does anyone have an idea about this?

Hi Tom,

welcome to the forum!

You are also invited to our German partner forum TeXwelt.de if you like to talk in German about TeX and TikZ.

As I'm a bit allergic now to flickering commercial advertising on goLaTeX, I prefer to post my answer here instead. It's a font issue, independent of TikZ. You can verify it with the same node directly in a frame.

And try using instead of the serif theme:

\usefonttheme{professionalfonts}

to not let beamer change the font, you will see that in that case there's no overlap. Perhaps see you on TeXwelt too? It's a new engine with quality sorting and fine topic sorting and there are great TeX connoisseurs who are friendly and welcoming.

Hello Stefan,

thank you very much for your help. I changed to \usefonttheme{professionalfonts} and it works fine.

I do still not understand what is \usefonttheme[onlymath]{serif} for and why it works perfectly with article but not with beamer.

Perhaps see you on TeXwelt too? It's a new engine with quality sorting and fine topic sorting and there are great TeX connoisseurs who are friendly and welcoming.
Stefan

I'll take a look on it, thanks for your hint.

Tom
