In a previous question, I asked about how to add extra margins for todo notes without affecting the original geometry of the page. The answer by Steven B. Segletes is satisfactory, but the output is not as intended with TeXstudio. The PDF generated seems to clip the content so that the page size stays almost the same.
Here is how the output is with the PDF taken as genreated
Here is how the output is after modifying the page size using an external PDF editor
TeXstudio generates the PDF correctly but crops it to be as close as possible to an A4 paper. Is there a way to force TeXstudio to generate the PDF in its real size and not crop it?
