When using the crop package with the frame option, SyncTeX' inverse search always seems to be a bit off.
Here is a MWE:
\documentclass[10pt,a5paper]{report}
\usepackage[a4, center, frame]{crop}
\begin{document}
Foo
Bar
Baz
\end{document}
Without the frame option, inverse search works normally but with it, inverse search always jumps to the \end{document} line.
There seems to be a duplicate which, unfortunately, does not have an answer.
Note: I removed most of the original question since it isn't relevant anymore now that I found a MWE.
