Delay when yanking or deleting to non-blackhole registers in daemon mode

[mgwio]

Description

Running emacs in daemon mode and connecting with emacsclient causes a delay when executing commands that store to the default (dd) or other non-blackhole register ("aD).

When run without daemon, this problem does not occur. When run with daemon/emacsclient, yank/delete to blackhole register ("_dd or "_yy or "_D...etc) does not observe this problem.

Here are a few clips of what I mean. The gifs are a bit choppy but I think the delay is still pretty evident in the ones using emacsclient. You can see that movement (jk), undo, and "_dX (blackhole register commands) still happen instantly.

With daemon in GUI (emacsclient)

Without daemon in GUI (emacs)

With daemon in terminal (emacsclient)

Reproduction guide 🪲

• Start Emacs --daemon
• Connect to instance with emacsclient (happens in both graphical and terminal)
• Any yank or delete to a non-blackhole buffer

Observed behaviour: 👀 💔
Delayed operation by about a second, no matter file size

Expected behaviour: ❤️ 😄
Operation to happen 'instantly', a la vim or non-daemon emacs
