Steps to reproduce

bug in Image.asset when specify a color – a thin boundary appears around the image. Depending on the width and height values, it will either render correctly or show the boundary (this tends to happen when dimensions are odd numbers).

This only happens with Impeller enabled; disabling Impeller makes the issue disappear.

Flutter version: 3.32.4

Repro on emulators:
• Pixel 8 Pro (API 30, Android 11)
• Medium Phone (API 35, Android 15.0)

It’s not yet confirmed whether this also occurs on physical devices.

Expected results

Expected behavior: The black image should be rendered correctly without any visible boundary artifacts.

Actual results

Actual behavior: The image is rendered with a black boundary around it. Depending on the device and image, that boundary may appear even more pronounced.

Code sample

Scaffold(
...
  body: Center(
        child: Image.asset(
          "assets/images/google.png",
          color: Colors.black,
          width: 187, // random odd numbers
          height: 187, // random odd numbers
        ),
      ),
    ); // Scaffold
