Description Brent R Brian 2019-03-06 18:11:37 UTC
Created attachment 1541556 [details]
Large document, OCR converted from scanned Google Book

Description of problem:

When editing large documents, Libreoffice often locks up.

Version-Release number of selected component (if applicable):

libreoffice-writer-6.1.5.2-2.fc29.x86_64

How reproducible:

Frequenty

Steps to Reproduce:

1. Spelling / line break corrections

Comment 1 Caolan McNamara 2019-03-06 21:20:32 UTC
Seems to load and layout quickly, and on first guess, it seems the spell checking lock things. What's supposed to happen IIRC, is at the end of spell checking a paragraph, more spell checking is suspended to deal with user events, so spell checking is idle. Maybe that has come unstuck.

Eventually the document unlock and then scrolling around is speedy

I make several passes through documents, I have done over 1,000 of these historical "restorations".  This is the largest, and the first, document that has caused LibreOffice to "stop responding" and have to be cancelled.

Process is something like:

* Turn off spell check.
* Remove OCR miss conversion artefacts.
* Use RegEx search to find [a-z]\p\p[a-z], broken line (across page break) that python script did not catch.
* Characters that where the font "oddities" cause miss convert 0 & O, 1 & l, W & \V, etc
* etc

During the process above writer will "stop responding", and I have left it over-night, it never responds again.

I have learned to do frequent saves.

That's something different then what I was looking at, which was just a temporary situation. So, its not sufficient to load it, editing is required. If I randomly type into the document at random locations and join some arbitrary paragraphs it doesn't lock up so I can't find the specific scenario that reproduces the lock

Comment 4 Brent R Brian 2019-03-07 21:20:52 UTC
Testing a theory, seems Nautilus (Gnome) and LibreOffice both miss-behaved (calc as well) ... but only on mouse clicks???

So, I tested the batteries in the wireless mouse ... 1.06v ... replaced them ... so far so good .... ???

Mouse isn't it.
