Thanks for the report, @jvanburen. I'm having trouble reproducing this problem, so I'm wondering if you could share a bit more details. Does this happen every time you press cmd-+ or randomly? Does this happen for every PDF file or only some (if only for some, can you share a link to that PDF)? Does this happen if you just open a PDF and don't use the latex package to generate PDFs? Did this problem start happening recently (i.e. with a recent update of the pdf-view package)?

It's a new issue (updated both OS X and atom-pdf-view). It occurs every time I press cmd-+ on PDFs generated by pdflatex. I can test it with other PDFs and get more info tomorrow.

Thanks for the details. :bow: I'm still having trouble reproducing this (by just opening a PDF and pressing cmd-+), but I just pushed a new version which should hopefully prevent this from happening. Give it a try and let me know if you can still trigger that error.

Checking back in, it seems the latest update fixed the issue, thanks!
