Description birnbach@posteo.de 2021-05-03 20:45:40 UTC

Description:
When activating the "track changes" and "show changes" option, NC will strike through text that is deleted and underline text that is added. Sometimes the "show changes" function keels over and gets everything wrong. In the documents I work with, all available text gets marked as new. About half of the text is missing and everything is garbled.

Steps to Reproduce:
It is unclear how to reproduce this bug. Amidst editing in "track changes" mode the displayed page stops making sense.

Present problem may have to do with numerated lists edited in "track changes" mode. Please refer to the enclosed RTF file which opens fine on MS Word on Mac, versions 2011 and 2019.

Actual Results:
Text is almost completely marked as edited. From some edit point on, text is garbled. Large portions of the text have disappeared.

Expected Results:
Deleted text should be in strike through, inserted text in underline.


Reproducible: Always

Confirming in:

Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community

Change tracking in RTF format is quite underdeveloped.

Side note: attached document if converted to docx with Word, looks exactly as it should in LO too.

> Side note: attached document if converted to docx with Word, looks exactly as it should in LO too.

True. Saving the DOCX as RTF in LO, closing and re-opening crashes it again.
Saving the DOCX as RTF in Word and opening it in LO also crashes it.

This seems to suggest that LO has an issue with tracked changes in RTF files. 
An issue that Word has not.

Please note that this functionality is quite relevant for use in official processes and communication. I myself am a patent attorney and use it for submissions to patent authorities. 

As public administrations move towards LibreOffice this issue might deserve a little more attention.
