Description
Steps to reproduce
- Build the Flutter application in release mode.
- Run the application on an Android device where the issue can be reproduced. The issue was reproduced on an Infinix X6835 with Impeller enabled.
- Ensure Impeller is enabled.
- Force-stop the application to ensure a cold start.
- Launch the application and measure the time until the first screen becomes usable.
- On the affected Infinix X6835 device, cold startup takes approximately 5–6 seconds.
- Repeat the same test with Impeller disabled on the same device.
- Startup is significantly faster with Impeller disabled.
- Compare the attached Flutter startup traces (
start_up_info.jsonandstart_up_timeline.json) from both configurations. - this is the gpu of device infinix x6835 MediaTek Helio G37
the first 2 files are with impeller enabled
start_up_info.json
start_up_timeline.json
the last 2 files are with impeller disabled
start_up_info.json
start_up_timeline.json

Timeline Traces
Timeline Traces
I collected Flutter DevTools timeline traces on the affected device with the performance overlay disabled.
I have attached startup traces for both configurations:
- Impeller enabled
start_up_info.json
start_up_timeline.json
- Impeller disabled
start_up_info.json
start_up_timeline.json
The Impeller-enabled and Impeller-disabled traces were collected from the same device and application to allow comparison of the startup and rasterization behavior.

@abdullah517 Thanks for the detailed report. Could you please provide a minimal reproducible example (main.dart file) and confirm whether the issue is still reproducible on the latest stable Flutter release? Also, could you please provide a video demonstration of the issue? This will help us reproduce and investigate the startup performance difference with Impeller enabled.

@abdullah517 Thanks for report. An existing issue is already tracking this problem. Closing this issue as a duplicate of #175577, which tracks the same slow cold/warm startup performance issue caused by Impeller on Android devices. Please follow/track #175577 for further updates.
