It turns out that this function is only hidden by FB. The method is to close the security option at the edge of the security zone to be superimposed with reality, but it is still hoped that it will become a functional option to facilitate adjustment of transparency.

The system should fix the "realistic overlay" mode option
Now the system has a transparent layer overlay mode. As long as it is at the edge of the safe zone, it can be superimposed with reality, but the transparency is very difficult to control and not fixed. I propose to make this transparent overlay into a fixed mode, and the transparency of the direct reality can be adjusted. This superimposed display mode has the feeling of a different dimension invading reality, as shown in the figure is very cool.
