[Impeller] gradient rendering error on Samsung Galaxy A03. #152951
Description
Steps to reproduce
Context:
Getting info logs about Impeller being active by default on Android and causing app returns to the legacy OpenGL renderer on device that don’t have support for Vulkan.
This started happening after Impeller was enabled by default: flutter/engine#54156
The issue is avoided if you implicitly disable Impeller by adding the flag to the manifest:
<meta-data android:name="io.flutter.embedding.android.EnableImpeller" android:value="false" />
Pre-requisites
- Ensure Xcode 16.0 Beta 4 is installed.
- Flutter (Channel master, 3.24.0-1.0.pre.465)
- Using an Android physical device without vulkan/impeller support.
Steps to Reproduce:
- Clone the Wonderous app repository from GitHub.
- Navigate to the root directory of the project and launch the app targeting a device using the command
flutter run - Run the app on an Android physical device that doesn’t have Vulkan support (to check if a device has Vulkan support you can use this app)
- Navigate through different screens of the app.
- Monitor the logs for errors/warnings/info and check the UI.
Expected results
The Wonderous app should run smoothly on the device without any errors in the logs and without graphic errors.
Actual results
The following error appear in the logs:
I/flutter (20951): [IMPORTANT:flutter/shell/platform/android/android_context_vk_impeller.cc(67)] Using the Impeller rendering backend (Vulkan).
The UI of the app shows graphical errors (see screenshots on the section below)
