2.2.0

[2.2.0] - 2026-07-20

Fixed

• Prompt corruption when dragging a split border: dragging a pane
  divider left the pane littered with stale prompt copies (especially
  with Powerline prompts such as oh-my-posh on macOS / Linux). Three
  fixes work together:
  • PTY resizes are deferred while the drag is in progress and flushed
    once on mouse-up, so the shell receives a single SIGWINCH (one
    prompt redraw) instead of a redraw storm racing the local reflow.
  • Panes whose size did not actually change no longer trigger a PTY
    ioctl or a local reflow on layout recomputes.
  • With OSC 133 / 633 shell integration active, the prompt + input
    rows are carried through a resize physically (pinned, not
    rewrapped) — the shell repaints them on SIGWINCH with
    cursor-relative sequences, which now line up. The prompt start row
    (OSC 133 A) is tracked so multi-line prompts stay stable too.
