Fixes: #157312 A simpler way to reproduce this issue: ```dart import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatefulWidget { const MyApp({super.key}); @override State<MyApp> createState() => _MyAppState(); } class _MyAppState extends State<MyApp> with SingleTickerProviderStateMixin { late AnimationController controller = AnimationController( duration: const Duration(seconds: 2), value: 1, vsync: this, ); @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( body: Center( child: FadeTransition( opacity: controller, child: Builder( builder: (context) { return GestureDetector( onTap: () { controller.value = 0.5; context.findRenderObject()?.markNeedsPaint(); controller.value = 0; }, child: Text("Click"), ); }, ), ), ), ), ); } } ``` The main reason is that updating the opacity with `markNeedsCompositedLayerUpdate` followed by `markNeedsPaint` causes it to be added to `owner!._nodesNeedingPaint` twice. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [ ] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
