Description

Add a new flag that allows users to override system prefers-reduced-motion setting

Who's implementing?

  • I'm willing to implement this feature myself

The problem

If Animations are disabled in Windows settings or Reduce Motion is enabled in macOS settings, there is no way to keep animations in Chromium.

研究方向
Investigate how Chromium handles the prefers reduced motion preference, particularly the existing command line flags like force prefers reduced motion. Look at Chrome's flag registration system (e.g., chrome/browser/flag descriptions.cc) and add a new flag similar to Firefox's ui.prefersReducedMotion. Ensure the flag overrides both system settings and existing flags. Check for any relevant code in chrome/browser/renderer preferences util.cc or similar files that map preferences to Blink settings.
