[Bug] C-x C-g to launch editor triggers visual artifacts

Inizia dal percorso di avvio dell’editor Ctrl-x Ctrl-g e riproduci il problema con le combinazioni di terminali, editor e tmux elencate. Confronta la gestione dell’input dopo l’avvio di vim o nano, quindi verifica che i caratteri vengano registrati normalmente, che i due punti e Enter funzionino correttamente e che l’uscita ripristini un prompt pulito per comandi-codice.

Summary

The Ctrl-x Ctrl-g shortcut, which launches the $EDITOR from the terminal, fails to register typed characters properly, it feels laggy and after pressing Enter multiple times or typing a colon (:), the terminal fills with colored lines and other visual artifacts. This disrupts the session and often requires multiple Ctrl-c keystrokes to exit CommandCode.

Environment
Operating System: Ubuntu 24.04.04 LTS
Shell: Bash 5.2.21
Terminal Emulators Tested: gnome-terminal, st
Terminal Multiplexer: tmux 3.4 (optional)
Editors Tested: vim 9.1, nano
No tmux used in some test runs

This may be a known issue, but no existing references were found.

Expected Behavior

Typing characters should register immediately without lag or delay.
Typing a colon should behave normally (e.g., entering command mode in vim).
The terminal should remain clean and stable during the editing session.
Exiting the editor should return cleanly to the command-code prompt without visual artifacts.

Actual Behavior

Laggy/unresponsive keyboard input
Characters not registering properly
Terminal fills with colored lines/visual artifacts after pressing Enter multiple times or typing a colon
Disrupted session requiring multiple Ctrl-c to exit
Unstable terminal state

Steps to reproduce the issue

Open a terminal (gnome-terminal or st).
Press Ctrl-x Ctrl-g to launch the editor defined in $EDITOR.
Attempt to type text in the editor.
Press Enter several times or type a colon (:).
