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.
From what I understood is that the functionality that pastes selected text with middle-click is coded deep in the Linux kernel, so it doesn’t even use a clipboard and it would be hard to get rid of this functionality. As others mentioned, using normal copy-paste commands (ctrl+shift+c) shouldn’t be a problem because it uses a clipboard.
