   This issue might be a duplicate of existing issues. Please check:

   • Clipboard copy fails in Zellij and other multiplexers (OSC52 written to stdout instead of /dev/tty) #12082: Clipboard copy fails in Zellij and other multiplexers (OSC52 written to stdout instead of /dev/tty) — same root cause (OSC52 not reaching the terminal emulator through a multiplexer), and includes a detailed technical analysis and proposed fix
   • Copy Text "Copied to clipboard" does never work #7048: Copy Text "Copied to clipboard" does never work — same symptom (notification appears but clipboard is not updated) in Ghostty

   If your issue is covered by one of these, consider adding a comment there with your specific environment details (SSH + tmux + Ghostty) rather than a new issue.

   This resolved my issue @thdxr:

   Ghostty: allow OSC52 clipboard access

   copy-on-select = clipboard
   clipboard-read = allow
   clipboard-write = allow
   
   

   tmux: allow OSC52 passthrough

   set -g allow-passthrough on

   If you're on macOS, clipaste may help — it's a background daemon that normalizes the screenshot clipboard so image paste works in terminal AI tools. Also supports SSH remote paste.

   brew install hqhq1025/clipaste/clipaste
   brew services start clipaste

   For SSH remote: clipaste ssh-setup user@host

   I'm not using ghostty, i'm using iterm2, ssh into linux, then running tmux. But i found this thread looking for answers to this and set -g allow-passthrough on was what I needed.

   ❯ cat ~/.tmux.conf
   # ==================================
   # == COMMON SETTINGS (for all OS) ==
   # ==================================
   # These settings will apply to both Linux and macOS
   
   set-option -g mouse on
   set-option -g set-clipboard on
   set -g allow-passthrough on
   
   # Enable OSC 52 clipboard (works for mouse copy, even over SSH)
   # This tells tmux to use the terminal's clipboard
   set -as terminal-overrides ',*:Ms=\E]52;%p1%s;%p2%s\a'
   
   # Pane navigation

   bind k select-pane -U    # up
   bind l select-pane -R    # right
   
   # Window navigation

   bind m next-window
   
   
   # ====================================

   # Change status bar to teal if on dev-box
   if-shell "[ $(hostname) = 'dev-box' ]" \

       "set-option -g allow-passthrough on"
   
   # -----------------

       bind-key -T copy-mode-vi v send-keys -X begin-selection; \
       bind-key -T copy-mode-vi y send-keys -X copy-pipe-and-cancel 'pbcopy'; \
       bind-key -T copy-mode-vi Y send-keys -X copy-pipe-and-cancel 'pbcopy' \; \
       bind p run 'pbpaste | tmux load-buffer - ; tmux paste-buffer' \
   "

   # Split panes using current directory

   bind % split-window -h -c "#{pane_current_path}"
   
   # Open new windows in the current directory
   bind c new-window -c "#{pane_current_path}"
   
   

   is my full tmux

    Does opencode even support tmux clipboard in the first place without using xclip? I want opencode to copy to the tmux clipboard without messing with the system clipboards

    This resolved my issue @thdxr:

    Ghostty: allow OSC52 clipboard access

    copy-on-select = clipboard
    clipboard-read = allow
    clipboard-write = allow
    

    tmux: allow OSC52 passthrough

    set -g allow-passthrough on

    Source: https://petar.dev/notes/copypaste-for-opencode-with-ghostty-and-tmux/

    This solved for me as well. have to use ghosty and tmux for the full terminal wire protocol.

    Solution found: install xclip

    sudo apt install xclip
    My environment:

    • Ubuntu 26.04 + Ptyxis + Wayland
    • OpenCode 1.15.5
    • No multiplexers (tmux/zellij)

    Why it works: OpenCode seems to use xclip as a fallback for copying to the clipboard when OSC52 fails (which happens in certain Linux terminals with Wayland).
    Before this, auto-copy-on-select showed "Copied to clipboard" but never reached the clipboard. After installing xclip, it works perfectly.
    Note: the solution is simple and doesn't require changing terminals or disabling Wayland. Hope this helps other users with the same issue.

    This worked with these settings at this point #15907 (comment) then it stopped working this is Ghostty related.
