Copy/paste is very unreliable WHEN COPYING FROM COMMENTS INTO THE TEXT. It often produces the previous clipboard content. I.e. you cut A, paste A, cut B, paste A (rather than B). If you undo, cut B again, then paste B. THE NORMAL COPY/PASTE (text to text) works. (Edits added in caps)
This is on Version: 184.108.40.206, Build ID: 1:6.3.3-0ubuntu0.19.10.1. (Gnome)
It seems to happen whether you use keyboard shortcuts or right-click menu.
I’ve seen some similar posts about clipboard problems, but they seemed to be to do with Windows, whereas this is on Ubuntu.
Any ideas what’s wrong here?
