Repository: flutter

Labels: framework,has reproducible steps,P2,found in release: 3.3,found in release: 3.6,team-framework,triaged-framework

## Steps to Reproduce

1. Execute `flutter run` on the code sample.
2. Move your cursor.
3. Observe the square is not placed in the middle of the precise system cursor.
4. (When doing a scroll gesture on my trackpad the positioning improves???)
