Quoting Pedro Beja <[email protected]>:
I'm closing this bug now since it seems to be fixed.
Did you try? Which version of evince?
If you can still reproduce it feel free to reopen and provide more info.
I opened the file http://mirror.ctan.org/macros/latex/contrib/pdfcomment/doc/example_math_markup.pdf with evince 3.14.1-2 (Debian 8) and 3.22.1-2 (Debian 9). I'm not able view nor edit the comments, i.e. hovering the pointer over the highlighted formulas does not show anything. Neither does clicking on them have any visible effect.
