--- Comment #2 from me@haravikk.com me@haravikk.com --- Under System Preferences -> Displays -> Arrangement I repositioned the smaller display, and moved the menubar from it over to the larger display (Apple really needs to change this now that all displays get a menubar).
And yes, I have displays configured with separate Spaces.
