Description daniel.semler 2015-06-11 14:44:27 UTC
I have a document of 49000 words (269000 chars) in Ancient Greek and English. It has a lot of Comments in various places. I can only estimate the number but I would say a few hundred ( I don't know how to get a count of them ). If I check the View -> Comments box then typing is very very slow. If I turn off the check box typing is fine. I, of course, need the comments so the only workaround I have is to continue the work in a separate file.

BTW, the version above says but in fact the version report by LO is

Producing a testcase should be a simple matter of creating a large enough document with a bunch of comments in it. I don't believe I can share the document I hit this on, so hopefully it's easy to repro. Let me know if not and I'll see if I can produce a document I can upload.

Unfortunately we can't find & replace text in comments, otherwise this would be enough to provide a testcase: https://wiki.documentfoundation.org/QA/Bugzilla/Sanitizing_Files_Before_Submission#Sanitize_file_text

Now you would have to unzip the .odt and find & replace inside the content.xml and zip again..

document with comments

See attached comments.odt document.  If slow-down is not noticeable then perform Tools | Update | Page format.  You should then notice a significant slow-down in scrolling speed.  Trying to enter text in a comment box makes LibreOffice unuseably slow (see editable comment box on 2nd page).
