Steps to reproduce
Run the following minimal reproduction sample (standard Flutter IconButton gallery example)
Expected results
All IconButton variants render with a clean, fully closed circular border as per Material 3 specification.
Actual results
The circular border of IconButton.outlined appears visually broken — the outline is incomplete or clipped, making the button look malformed. This issue is only reproducible with Impeller enabled (default renderer on Android). Running with --no-enable-impeller resolves the issue completely, which suggests this is an Impeller rendering bug.
