Every time I unlock my 2018 15" MacBook Pro, the Touch Bar displays a `x` button and the `Esc` button, irrespective of whatever the Mac is running (it is not displaying the address toolbar on Chrome for example). I must always touch the `x` button to remove it, and display the current content for the Touch Bar.

I checked for running applications with system monitor, and nothing was wrong.

Is there a way to know what is currently controlling the Touch bBar? I want to delete this, and I cannot find it.
