Ctrl+V image paste shows no placeholder on Wayland despite successful clipboard read

[MasterMind7777777]

What feature would you like to see?

Problem

In the TUI, pressing Ctrl+V after copying a PNG succeeds according to the
paste_image_as_png span, yet the composer never shows the [image …] placeholder and no
image is attached. There’s also no user-visible error.

Steps to Reproduce

1. Launch Codex TUI on a native Wayland terminal (kitty Wayland backend).
2. Copy a PNG (I used a fresh screenshot).
3. Focus the composer and press Ctrl+V.
4. Observe that nothing appears; retrying yields the same result.

Expected

An image placeholder should appear in the composer, just as it does on X11 terminals.

Actual

The log shows the clipboard read finishing successfully, yet the composer stays unchanged
and no attach_image entries appear. Because the Ctrl+V handler ignores the Err from
paste_image_to_temp_png(), any failure in that helper is swallowed, leaving the paste
as a silent no-op. Please add Wayland-safe image paste support and surface the failure so
users know what happened.

Silent error

The Ctrl+V handler in codex-rs/tui/src/chatwidget.rs:1015-1035 calls
paste_image_to_temp_png() inside if let Ok((path, info)) = paste_image_to_temp_png().
Because the Err branch is never matched, any failure immediately exits the handler
without logging or UI feedback. The helper (codex-rs/tui/src/clipboard_paste.rs:121-135)
does return detailed PasteImageError::IoError/NoImage/..., but since the caller ignores
the Err, those messages never reach the log or the user, so the paste simply appears to
do nothing.

// codex-rs/tui/src/chatwidget.rs:1015-1035
KeyEvent {
        code: KeyCode::Char('v'),
        modifiers: KeyModifiers::CONTROL,
        kind: KeyEventKind::Press,
        ..
} => {
  if let Ok((path, info)) = paste_image_to_temp_png() {
    self.attach_image(path, info.width, info.height, info.encoded_format.label());
  }
  return;
}

paste_image_to_temp_png() returns a Result, but only the Ok branch is handled. Any Err
immediately returns from handle_key_event with no log or UI feedback.

// codex-rs/tui/src/clipboard_paste.rs:121-134
pub fn paste_image_to_temp_png() -> Result<(PathBuf, PastedImageInfo), PasteImageError> {
  let (png, info) = paste_image_as_png()?;
  let tmp = Builder::new()
    .prefix("codex-clipboard-")
    .suffix(".png")
    .tempfile()
    .map_err(|e| PasteImageError::IoError(e.to_string()))?;
  std::fs::write(tmp.path(), &png).map_err(|e| PasteImageError::IoError(e.to_string()))?;
  let (_file, path) = tmp
    .keep()
    .map_err(|e| PasteImageError::IoError(e.error.to_string()))?;
  Ok((path, info))
}

The helper maps failures to PasteImageError, but because the caller discards
the Err branch, every error path becomes a silent no-op, so nothing reaches the logs or
the user.

Same; paste no longer works (I'm on Ubuntu). The bug was introduced in 0.45; I reverted to v0.44 which does not have this issue.

@PaulFidika Are you on wayland or x11? I was not working for me even on 0.44 so there could another problem that prevents pasting image.

[donnielrt]

I can confirm that pasting on Wayland hasn't worked for me in any previous versions (0.44 or earlier).

For anybody struggling with the lack of image support in the linux codex CLI, I just found a workaround online to this that solves the problem perfectly! While paste (Cmd+V/Ctrl+V) isn't working, dragging and dropping an image into the terminal works!

+1.
Does not work for me.

Just pasting an image without the placeholder showing still does not provide the image to the context. I tried this here twice.

If there is no placeholder that means that image failed to be processed and was not added to context.
