[shrink] makes clickable part of links appear totally offset from their corresponding texts

[liar666]

Hi,

I'm using Emacs' org-mode to generate Beamer presentations. When I use [shink] on some slide, then the clickable parts of links appear totally offset from their corresponding texts.

As noticed by the org guys, the generated .tex code is valid. The bugs seems to be in Beamer itself.

MWE: If you apply org-beamer-export-to-pdf to the following org file: test.org.txt you get the following tex file: test.tex.txt If you compile it and open the resulting PDF (in Evince or PDF.js or any other PDF viewer), you'll find that blue text is not clickable. The clickable areas are generally slightly above the text of the link (at least with shrink=10), or at almost "random" position (with shrink=60).

It seems shrink applies to the text overlay, but not to the clickable overlay.

There is a reason why the shrink option is called "evil" in the beamer user guide :)

See this comment https://tex.stackexchange.com/questions/516345/shrinked-frames-with-hyperrefs-in-beamer-have-displaced-hyperlinks#comment1305643_516345

That's a general problem with such transformations. You will see the same problem e.g. with combining pages with pgfpages etc.

Instead of using the evil shrink option, you could use a smaller font size. You could even do this automatically using the fitting library of tcolorbox:
