Can't copy more that 1919 rows

Hello,

I’m running today into a paste special issue : (not seen before, I’ve recently upgraded to libreoffice 25.2.3.2, bundled in Debian 13)
Issue seen with special past, but seems the same with the regular paste

Reproduce step :
New calc document, empty
Select A1:A1919
Copy
Right click on another cell, Try to past special, it work fine
Select A1:A1920
Copy
Right click on another cell, Try the past special, got [No selection possible] Note that the regular paste is not included in the dropdown neither.

Expected behaviour :
Should be able to always paste, as it was working in debian 12

Thanks

EDIT : pasting is not the issue here, because copying from calc to a text document work up to 1919 lines, but not beyond that

see Pasting formulas from calc into calc - #13 by fpy

FYI echo $XDG_SESSION_TYPE give x11
also running

SAL_USE_VCLPLUGIN=gen libreoffice

don’t change the issue, even if I still get the option to paste, nothing happens

And the double Ctr+C trick neither did the trick

EDIT, I’ve found that the copy is indeed the culprit, because pasting the content to another application work below 1919 lines, but not beyond that

In my case, using xfce, activating clipman (ie get it in the taskbar) and ensuring it’s disabled (right click on it icon in the taskbar, then ensure that Disable is ticked, allowed me to copy in calc using a double Ctrl-C

it works, but if anyone have an explanation on what it happening, I would be very glad !

maybe file a bug there : panel-plugins:xfce4-clipman-plugin:bugs [Xfce Docs]

Yes, was thinking about that tonight !

No idea about the specifics of clipboard destruction performed by clipman, but in general, it seems to modify the clipboard for unknown reason. Even if a clipboard manager reads the clipboard, it must not:

  1. Change the registry content (like here); and
  2. Try to read all existing clipboard formats, like in another issue (tdf#159755, fixed in klipper, but needs fixes in every problematic manager - multiple are affected) - it must only read what it knows.

Many clipboard “managers” behave naively, assuming that clipboard is a simple thing (they don’t even consider that often, applications do not generate all the clipboard content in advance, but only advertize it, to be generated later on request, for performance reasons), and ruin clipboard interaction.

Ok, got the solution !
See Can't copy more than 1919 row in LibreOffice Calc (#121) · Issues · Panel Plugins / xfce4-clipman-plugin · GitLab which is tracking a but in xfce.
You will need some manual building, but “it work on my machine”, using a Debian 13 Up-to-date with the repo, as in today (12 august 2025)
We still need to be waiting for the fix to be broadcasted with newer version.

So yes, it modified the clipboard by taking ownership. Sigh.
