Reduced Motion + React-Freeze Bug Analysis

Problem Summary

Issue: Gray screen appears on Android when users enable "Reduce Motion" accessibility setting and quickly swipe between channels.

Root Cause: Animation updates (translateX) arrive while components are frozen/unregistered, causing updates to be lost and components to render with stale values.

Context: I've been working on this issue and there are currently three different solutions in play. I want to present the situation to the team and get alignment on the best approach.

React Native Reanimated Microtask Bug

Reanimated Animations Stalling?

How Szymon and I traced it to an Infinite Loop & Fixed It

tl;dr – A tiny helper (infiniteThenable) inside react-freeze made React’s Fabric scheduler loop forever, so the JS → UI microtask bridge never got a chance to flush. We patched the scheduler to flush manually and replaced the culprit with React 19’s Offscreen – animations are smooth again.

1. The Symptoms

  • Animations powered by Reanimated randomly froze.
