Tested with LockDown Browser v2.1.6.01
A screen capture proof window is visible to the user but excluded from screenshots, screen recordings, and screen shares on macOS.
Fracture creates a private window using a system-level privacy mechanism on macOS. This excludes the window from screen capture and window enumeration APIs. The same mechanism is used by macOS for system-level UI elements.

Fracture runs a native floating overlay that sets the macOS window privacy flag. It is 100% excluded from screen capture feeds, window lists, and proctor recordings.
