Description

When I'm at a new prompt with /n in the TUI, it occasionally stops printing the characters I'm typing, then suddenly shows them and continues to work until it pauses printing characters again. When deleting with backspace this can be annoying because you remove too much because it seems the character is not deleted. This is before engaging the LLM, so it's the initial prompt. The freezes last for around 1-3 seconds.

This is on windows terminal in a wsl session.

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

  • #5361: TUI freezes for ~10 seconds periodically on WSL2 (regression in v1.0.129) - describes similar buffering of input where characters are buffered during freezes and appear after

This is particularly relevant if you're on OpenCode v1.0.129 or later on WSL2. The freezing behavior could explain the intermittent pauses in character echoing you're experiencing.

Feel free to ignore if your specific case differs from this.
