Flutter's macOS engine only sends mouse-moved events to the key window by default. The borderless audience (beamer) window deliberately never becomes key, so chart tooltips never appeared on the second screen, and hover styling stuck around whenever a window lost key status before the exit event arrived. Track the mouse whenever the app is active instead, for both the main window and every secondary window. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
