When you enable image protection in the WebGL settings, SupLogin intercepts the WebGL read requests from websites and applies special noise to them. The noise value remains consistent within the browser profile, meaning that all WebGL image reads in this profile will be modified in the same way. For example, the same WebGL image on different pages will be altered in the same way, and the same image across different browser sessions will also be altered consistently.

This ensures that the unique fingerprint of a browser profile remains persistent. It is generally recommended to enable this feature by default.

SupLogin antidetect browser can randomize the WebGL fingerprint, so each browser on the same computer will generate a different WebGL. If WebGL is disabled, each browser will use the default WebGL settings of the current computer.
