Hello! I have encountered a very troublesome bug where some images in my document are repeatedly cut off. (If I edit any text in the line the images are in, or above, the full image gets restored, but are cut off again when I close and re-open the document) This problem has led to significant problems with PDF documents I have been producing, because the lower edge of the images that get cut off contain crucial information. The bug is very similar to a report I found on Stackoverflow that was posted almost 10 years ago (crop - Why do my pasted images looked cropped in LibreOffice Writer? - Stack Overflow).
Since this is such a significant bug to me and nothing I have tried has reliably solved the problem, I would like to file a big report. However, the document that is causing the most reproducible version of this problem is my PhD dissertation, which is quite long and I am not sure I want to post it publicly yet anyways, since it is not finished. The problem disappears if I shorten the document. How can I report this bug if the file required for reproducibility is long and I am not willing to publicize it?
