Description

When a tool call triggers a permission dialog (e.g., bash command, file edit), the UI becomes unresponsive. The input area seems to freeze and keyboard input is sluggish or ignored.

This appears related to #5820 (autocomplete/permission conflict) and #3846 (no response to user input), but is a distinct symptom focused on the permission dialog itself causing unresponsiveness.

Symptoms

  • Input field becomes unresponsive when permission dialog appears
  • Keyboard events are delayed or not processed
  • UI may show visual artifacts or text appearing in wrong places
  • Sometimes need to wait several seconds before input is accepted

Possible Causes (from code analysis)

  1. Keyboard event conflicts: permission.tsx has its own useKeyboard handler that may conflict with other handlers in session/index.tsx
  2. Diff rendering blocking: Large diffs in the permission preview (EditBody component) could block the main thread
  3. State synchronization: Permission state syncing via useSync might be causing render blocking

Relevant Code Locations

  • packages/opencode/src/cli/cmd/tui/routes/session/permission.tsx - Permission prompt component with keyboard handler
  • packages/opencode/src/cli/cmd/tui/routes/session/index.tsx:1024-1033 - Permission rendering and prompt disable logic
  • packages/opencode/src/cli/cmd/tui/component/prompt/index.tsx - Prompt component that gets disabled during permissions

OpenCode version

1.0.223

Steps to reproduce

  1. Start opencode
  2. Ask the agent to run a bash command or edit a file (with permission set to "ask")
  3. When the permission dialog appears, try to interact with the UI
  4. Observe sluggishness/unresponsiveness

Operating System

macOS

Terminal

Ghostty / iTerm2

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

  • #5820: Autocomplete dropdown conflicts with permission dialog - visual overlap and keyboard event capture
  • #3846: No response to user input - general UI unresponsiveness with keyboard input
  • #4061: Session hangs after file write tool execution with massive latency spike
  • #4092: Better navigation of output and non-blocking agent permission requests

Feel free to ignore if none of these address your specific case.
