Original Pull Request: https://github.com/anomalyco/opencode/pull/10482

State: open
Merged: No

What does this PR do?

Fixes the textarea cursor not auto-scrolling when typing long prompts that exceed the visible area (maxHeight of 6 lines).

When typing beyond the visible area, the cursor would move but the viewport wouldn't follow, leaving the text invisible and causing black/empty spaces to appear.

How did you verify your code works?

The fix adds markDirty() and requestRender() calls to the onContentChange handler, matching the pattern already used in:

  • onPaste handler (lines 926-929)
  • TuiEvent.PromptAppend handler (lines 98-100)

This ensures the layout is recalculated and the viewport syncs with cursor position on every keystroke.

Fixes #10401
