Does this have something like a demo that can be used to reproduce the issue?
Yes, surprisingly although only for revelations:

Steam account required; there's a "Doweload demo" option half way down the page.
You should see a checkerboard pattern in the main menu with the commit, and then invisible characters after the first cut scene.
