I thought that Windows 7 don't get the screen curtain feature due to OS limitations. Only Windows 8 and later should get it. Please correct me if I'm wrong.

Edit: I got it. Quote from the changelog (alpha-19195):

• Added screen curtain, which when enabled, makes the whole screen black on Windows 8 and later. (#7857)

Yes just ahead of this in this very list was a change to stop profiles saving lots of stuff not intended from this functions point of view, I suspect that the code has broken the windows 7 opt out part of the routine.
