Text Overlays All on One Line in Libreoffice & Other Programs

One of our Manjaro installations on a Dell laptop has been having a weird issue with text, and copy-paste. If a paragraph (or even less) of text is copied over from libreoffice-still to an email window (eg: gmail in a chrome browser), the text all stacks up and overlays itself on to one line. It can also happen when copying from document to document, and the text will sometimes overlay itself inside one document as I am typing it, overwriting the next line on top of the first one.

This has been going on for longer than the past two stable updates at least, so I don’t really have a recent update set to refer to. Sometimes I can work around it by copying over one line at a time into the new document or email, and sometimes even that won’t work. The mouse cursor will not even move to the back of the line at that point, it stays stuck in the front of the line of text.

I’ve looked through the forum a few times but have not really seen anything that matches this issue, so I’m posting here. Any ideas as to where to check, or logs/output that could help to debug this? I’m happy to provide any help I can. The system is always up to date with latest upgrades and kernels, etc.

Thanks very much.

Are you using Wayland on the PC? Especially KDE + Wayland have been reported to show this or similar issues.

Please, post output of

inxi -Fazy

Also, have a look here:

I checked both of those links but they don’t seem to be my issue. I am using xfce and xorg - not using any Wayland settings.
Here’s my inxi -Fazy output:

I tried uninstalling and reinstalling libreoffice, but it had no noticeable effect. Seems weird since it happens in more than just libreoffice, and happens most often when copying into an email text window.

Is there some setting, or missing/corrupted library or file that might cause this copy-paste text to bunch up and paste all into one line inside a browser email ‘compose’ window? Maybe I’m looking in the wrong place, but not sure where to check. I have had no luck googling this one, nor can I find any thread like it here on the forum.
