研究方向
Investigate the rendering of CheckBox and RadioButton controls when FlatStyle is System and dark mode is enabled. Review PR #11857 which introduced dark mode support. The issue likely involves the system drawn text color not being updated. Look at the OnPaint or related methods in the CheckBox/RadioButton source code. Test with the provided steps to reproduce.
