It’s a known issue that there’s a delay when releasing Caps Lock. It’s really annoying if you use Caps Lock for capitalization. What happens to me is this: HEre is HOw it LIkes, because of the delay when releasing Caps Lock.

What fix worked for me :

Replace the entity of ctrl_modifier with below one inside. (Don't forget to change permission of file to edit and revert the permission to origin)

// This changes the <CAPS> key to become a Control modifier,
// but it will still produce the Caps_Lock keysym.
hidden partial modifier_keys
xkb_symbols "ctrl_modifier" {
          key <CAPS> {
              type="ALPHABETIC",
              repeat=No,
              symbols[Group1]= [ Caps_Lock, Caps_Lock ],
              actions[Group1]= [ LockMods(modifiers=Lock),
                                 LockMods(modifiers=Shift+Lock,affect=unlock) ]
          };
};

Then open your Tweaks and select "Make CapsLock act as additional..." for Keyboard Caps Lock behavior.

You should log out and log in again to see result.
