LOWriter 25.2 images, boundaries and lines disappear halfway in document

Bolderbast · February 12, 2025, 6:20pm

Hi,

I have a pretty elaborate Writer document (32MB, ~1100 pages, lots of tables, calculations, custom properties).

It was working great in LO Writer 24.8.4, but in 25.2.0.3 I am having issues with it.

In the first part of the document all is well, but from about halfway through the document, display is broken:

Images no longer displayed
Lines no longer displayed
Boundaries no longer displayed

I can confirm it is a display issue, because a PDF export looks fine.
Also, after rollback to 24.8.4 it display correctly.

OS: Arch Linux (fully updated)

Could it be some memory/cache limit I’m hitting? Or any other suggestions?

Thanks in advance for any help!

In which file format do you save?
Can you upload a small part of the document where the problem is present here
so someone can look at it and examine it. Thank you.

Thanks for your reply!

I save the document as ODT.

Uploading a small part does not seem to be useful. The issue starts at page 503. When I delete the first ~490 pages, the (new) first pages (which were previously broken) are now fine an the issue starts again at page 556.

I think the only useful option would be for me to share the entire file, but it contains a lot of Intellectual Property, so I don’t think I’m allowed to do so…

Tried renaming /home/patrick/.config/libreoffice to /home/patrick/.config/libreoffice.ori, to start with fresh settings, but that did not help.

Memory usage before opening the document:

               total        used        free      shared  buff/cache   available
Mem:           31819       14627       12191        4722       10181       17191
Swap:          32767           0       32767

Memory usage after opening the document:

               total        used        free      shared  buff/cache   available
Mem:           31819       15717       11094        5088       10554       16101
Swap:          32767           0       32767

So it’s not like I’m running out of RAM or anything.

The following also makes no difference:

Tools → Options → LibreOffice → View

Disabled “Use hardware accelleration”
Disabled “Use anti-aliasing”

OK.
Now only work with copies of your file.
First check whether all pages that do not display correctly have the same page styles as the previous ones.
Take a copy of the file and divide it in two approximately halfway through the pages.
Check whether the problem still exists in the second part. And so on.

And have a look at here from @mikekaganski :

It could also be a time problem.

Yeah, already made a backup copy of the file, just in case (it was the first thing I did) :-).

Regarding your suggestion about splitting the file, I am convinced it’s not something specific in the file.
In the original file, the issue starts at page 503. When I delete the first 490 pages, the issue should appear at page 13, but it doesn’t. I don’t even have to reload the file, everything is just right. Then the issue starts at page 556 (which was prevously page 1046).

When exporting to PDF, the entire document looks fine. So to me that suggests that some limit is crossed only for displaying the document (amount of memory used, amount of pictures rendered, amount of tables/calculations done, or something). But I’ll try to investigate further.

If anyone has some more troubleshooting tips, like how to get some debug output from lowriter, that might be helpful!
