Original Pull Request: https://github.com/anomalyco/opencode/pull/6084

State: closed
Merged: Yes

Summary

Adds a new config option tui.animations (default: true) that allows users to disable spinner animations in the TUI. When disabled, a static [⋯] indicator is shown instead of the animated spinner.

Motivation

Several users have reported issues with the spinner animations:

  1. Visual distraction - The animated spinner is visually intrusive for some users (#6008)
  2. Performance/CPU usage - Animations contribute to high CPU usage, especially on slower machines or when running on battery (#3990, #2083, #4804, #4818)
  3. Minimal environments - Users running OpenCode in TTY or minimal terminal environments prefer static indicators

Usage

{
  "tui": {
    "animations": false
  }
}

Design Decisions

Static indicator: [⋯]

The choice of [⋯] as the static indicator is subjective. The reasoning:

  • Brackets provide clear visual boundaries
  • Midline ellipsis (⋯) is a standard "loading/waiting" convention
  • Avoided emojis and complex Unicode to ensure consistent rendering across terminals and fonts, including TTY environments

Open to suggestions for a better static indicator if there's a compelling alternative.

Keeping it simple

This PR only addresses enabling/disabling animations. Speed adjustment (mentioned in some issues) is intentionally left out to keep the change focused and minimal.
