Description

When OpenCode TUI is suspended with Ctrl+Z, the terminal is resized, and then resumed with fg, the UI may return in a partially stale state (misaligned characters / incomplete redraw).

Plugins

No response

OpenCode version

v1.2.20 (reproduced on current dev before fix)

Steps to reproduce

  1. Launch opencode in terminal (TUI mode).
  2. Press Ctrl+Z to suspend the process.
  3. Resize the terminal window while in shell.
  4. Run fg to resume opencode.
  5. Observe the restored screen.

No response

Operating System

macOS

Terminal

Reproduced in local terminal session (reporter environment)

Expected behavior

After fg, TUI should fully repaint using current terminal dimensions.

Actual behavior

After fg, parts of the old frame can remain and rendering is not fully refreshed.

    Ran into this on linux as well. Using v1.4.0. Very annoying bug, would appreciate if a fix is merged soon.
