It seems like for at least a decade every application/framework has had their own paste buffer, and honestly I’m surprised this isn’t “just working” out of the box by now.
- Open Terminal
- Run pwgen, double click one of the passwords.
- Middle click in Terminal, the copied password pastes just fine.
- Switch back to Chrome, CTRL-V into the password field.
- Realize 5 minutes later when you can’t login with the user you’ve just created, it’s because the content you pasted into the password field was an URL you copied in Chrome 15 minutes ago.
And don’t even get me started on vim/neovim having yet another copy/paste buffer.
As far as I know that happens because in Linux ctrl+v and middle click pastes are stored in different places and are considered different things, in fact there’s a third way to paste which I don’t remember. But basically the middle click paste is used whenever you select a string, there’s no need to copy it, and the ctrl+v paste works when you do ctrl+c.
