A version of this that’s fooled me involves the multiple desktop feature in some graphical OSs (I think Windows calls them workspaces).
The entire point is to clear out your dock/taskbar this way but occasionally I’ll forget, heave a dramatic sigh, and begin troubleshooting before it hits me and I sheepishly return to my work.
