When I load a large LO Writer ODT file, and do a search to get to a page (or use Navigator or TOC), pages will move back and forth by themselves for up to a minute

This problem only started occurring in 7.3 and the previous version. If I load a large multi-hundred page ODT document, it loads fine. If I then do a Find (Ctrl-F), or ctrl-click on a Contents entry to get to a specific page, or use the navigator to get to a page, it goes to the page just fine. But then within a second it goes to the next page and then the next page. As if there was some unseen hand hitting the pgdn/pgup keys. If I try and regain control by clicking on the text and using the page up key to return to the page where the text was found, it continues to page down (or page up?) at random for about a minute. I can’t stop the pages from moving. It is like the machine is possessed! I don’t have to touch the keyboard. Just moving the mouse over the page seems to cause the problem (without clicking on the buttons). The only solution is to wait a minute for the poltergeist to leave. LOL
Has anyone else seen this with the latest version? It is very annoying. Should I hold a seance to find out who is messing with my document?
I am currently using Writer 7.3.0.3.
TIA

One thing I forgot to mention. When the pages are moving by themselves, the Navigator panel remains on the correct entry, the one with the page containing search text that was found.

Please enter the operating system you are using.

In which file format do you save your document?

Has anyone else seen this with the latest version?

No surely not, otherwise a number of inquiries would have already been received on this topic. Therefore it is difficult to make a remote diagnosis.

But there is a list of the most common error causes:

Try step 2 first.

It’s just your specific document that started to show it lately; the problem is inherent to all OOo/LO versions, and it may differ a little in specific circumstances; some changes like optimizations or improvements may increase or decrease the individual manifestations of this.

The core “problem” is the way we do the layout (asynchronously after loading document); that takes time, and not very fast; see e.g. tdf#141586, and tdf#140147 that pushed me to file that one, which discuss another aspect (restoration of last edit position) of the same problem. See comment 21 in the latter bug, where I argue that it was present in old versions as well, mentioning the search on this Ask site, and results pointing e.g. to version 4.4.

Yes, it could be a file loading problem on large files. If I load the document and leave it alone for say 5 minutes, and then start to use Writer, it behaves itself. It has to be a loading bug. I don’t see why loading the file in the background would affect the page being displayed because that should not updating the screen until its finished. It should only be loading the data and when finished it can update the stats like the page# for the current page etc, but not physically redisplay the page or move to another page during the loading process. It is very frustrating to see something take over the document and start paging through it at random without me being able to stop it. Maybe the document is haunted? LOL

BTW, I am using Win10.
