Flutter SDK (3.29.0) after lock screen

muhammadkamel · February 17, 2025, 12:30am

Hi everyone,

I’m facing an issue with the latest Flutter SDK (3.29.0). After I lock the screen and then unlock it, the UI text appears distorted, as shown in the image.

Has anyone else experienced this issue?

Is this Arabic fonts?

No, it’s English

I think you should file an issue.

As a quick fix I recommend disabling Impeller in AndroidManifest

<meta-data android:name="io.flutter.embedding.android.EnableImpeller" android:value="false" />

After upgrading to 3.29, the UI is broken.

After upgrading to 3.29, the UI is broken. If you touch the screen and move it, …it returns to normal. I just uploaded the version and kept the source the same. device Android GalxxyS24+ Flutter 3.29.0 • channel stable • https://github.com/flutter/flutter.git Framework • revision 35c388afb5 (6 days ago) • 2025-02-10 12:48:41 -0800 Engine • revision f73bfc4522 Tools • Dart 3.7.0 • DevTools 2.42.2 ![Image](https://github.com/user-attachments/assets/e0daf7b4-02db-4d82-bbc1-a15d30a843ce)

[This video showing graphical artifacts while painting images](https://drive.goo…gle.com/file/d/163VyXUC11t_BjngT4k5--E0Z60d1MLz_/view) was observed while running on the Impeller backend in profile mode against https://github.com/flutter/engine/commit/e57b5bac4244d09f9a4404d52c534a9c820d5915. The Vulkan renderer was in use: ``` E/flutter (12817): [ERROR:flutter/shell/platform/android/android_context_vulkan_impeller.cc(48)] Using the Impeller rendering backend (Vulkan). ``` I tried getting GPU info from https://vulkan.gpuinfo.org/download.php, but it wouldn't install on my TV: ``` adb: failed to install /Users/tvolkert/Downloads/vulkancapsviewer_3.32_arm.apk: Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113] ``` According to [`javax.microedition.khronos.opengles.GL10#glGetString`](https://developer.android.com/reference/javax/microedition/khronos/opengles/GL10#glGetString(int))([`GL_RENDERER`](https://developer.android.com/reference/javax/microedition/khronos/opengles/GL10#GL_RENDERER)) (called [here](https://github.com/tvolkert/photos/blob/69b77905f07f9e6db752ff7081754dfd38a5265c/android/app/src/main/java/dev/tvolkert/photos/PhotosChannel.java#L227) - basically I create a `GLSurfaceView` in order to then ask it info about itself), the GPU is a https://developer.arm.com/Processors/Mali-G52 In case it helps, these artifacts were also observed when I captured this systrace: https://drive.google.com/file/d/1bagpcY5wYprqMPmfTUJXeTAVuctbxHAv/view

Are you running on any of the chipsets listed there?
