I also just experienced this same bug on fresh install of Focal 20.04. I don't have Yubikey. Since the appearance of the window is delayed from whatever triggers it, I don't know what the cause is. The behavior is as other describes, a orphaned window on top left corner of screen, clicking the window results in whatever is underneath being clicked. Logging out and relogging makes the window disappear.
