Just upgraded to OS X Sierra.

When connected to a second monitor via AirPlay the menu bar of VLC still shows translucently. Had the same problem in Mavericks and found a work around, but that work around doesn't correct it in Sierra. I remember it was a simple preference change. Search here and tried the suggestions to no avail.

Thanks in advance.

Unless you are doing full screen on the second display, the menu bar will show. This is something that is more of a macOS behaviour. For details:

Yes I do indeed want to run in full screen mode. It is in the full screen mode I want the menu bar to disappear behind what ever I am playing on the 2nd monitor.
