This project is for demonstration purposes to show the bug in issue 79081 and to show a solution / workaround
The project will launch into a scene containing overlapping geometry which will replicate the issue. Hitting the tab key will toggle anti-aliasing on and off to demonstrate how this can help mitigate it.
Pressing space will switch to a scene containing no overlapping geometry which will not have any flickering. Pressing space again will return to the initial scene.
