I have a LibreOffice Writer 7.5 odt file (~100 pages, 3Mb). It contains cross-citations, styles, toc, figures and tables with captions, ~1000 comments, etc.
Whenever I open the file the comments are displayed with a 1-5-10 sec lag.
When they are visible I can see that Undo button is active with at least 3 items about style formatting.
When I save the file (with these undo items) it gets a bit larger in 20-30Kb each time…
I converted the .odt document to .doc and the latter is 32Mb of size, while the forme – 3Mb.
What’s wrong ?
