Dear Maintainer,

When running pdftocairo using :

pdftocairo -png -antialias best beamer.pdf

the output is "weird". Shapes appear to be correct, but fonts are
messed up in a way I don't quite understand. I tried it with multiple
pdfs coming from latex beamer and from latex article.

Not specifying -antialias gives a result that looks correct.

(Attaching the pdf file and the obtained PNG output for reference.)
