TUI cannot scroll up after session completes; exit prints subprocess stack trace #29221
Closed as not planned
Description
Description
After OpenCode finishes its work in the TUI, I cannot scroll up to review earlier conversation output. Trackpad/keyboard scrolling appears stuck or ineffective once the session is done.
On exit, the process also printed a Python traceback (via my agent-launch wrapper). The traceback may be from interrupt/cleanup during subprocess.wait, but the scroll regression is the primary bug.
OpenCode version
1.15.10
Steps to reproduce
- Launch OpenCode (in my case via
agent-launch -a opencode) - Run a session that produces multiple messages / tool output
- Wait for the agent to finish its work
- Try to scroll up to review earlier messages
- Exit the session
Expected behavior
- After the agent completes, I should still be able to scroll up through the full conversation history
- Exit should be clean (no traceback)
Actual behavior
- Cannot scroll up to review prior output after work completes
- On exit, a traceback was printed:
Traceback (most recent call last):
File "/Users/dhruvanand/.local/bin/agent-launch", line 441, in <module>
cmd = build_command(args)
File "/Users/dhruvanand/.local/bin/agent-launch", line 437, in main
args = parse_args()
File "/Users/dhruvanand/miniforge3/lib/python3.10/subprocess.py", line 347, in call
return p.wait(timeout=timeout)
File "/Users/dhruvanand/miniforge3/lib/python3.10/subprocess.py", line 1209, in wait
return self._wait(timeout=timeout)
File "/Users/dhruvanand/miniforge3/lib/python3.10/subprocess.py", line 1959, in _wait
(pid, sts) = self._try_wait(0)
File "/Users/dhruvanand/miniforge3/lib/python3.10/subprocess.py", line 1917, in _try_wait
(pid, sts) = os.waitpid(self.pid, wait_flags)
Note: agent-launch is a local wrapper that execs opencode in interactive mode by default; the subprocess frames may be from wrapper cleanup rather than OpenCode itself.

Can you share the agent-launch source? If you expect the TUI Session to be in the scroll back, that is not how it works. You can use the minimal mode interactively which will write to scrollback with

It's just a wrapper cli that runs the opencode command with some cli flags. The hang happens in opencode tui. Not expecting it in scrollback, but the scrolling functionality of opencode itself gets stuck

The error trace seems Python related and not opencode specific. Questions:
opencode <same-dir> --model <same-model>, noagent-launch?PageUp/PageDownwork?tui.json,OPENCODE_TUI_CONFIG, and whetherOPENCODE_DISABLE_MOUSEis set?github-actions commentedon Jul 26, 2026
