Splash screen on first run won't go away

Expected behavior

After first installation and token activation, this little splash screen is shown to tell us docker is up and running. I should be able to close that and move on with my life.

Actual behavior

There is no way to close that splash screen and it stays always on top of everything else, including my Dock, that stays hidden on the left side. Print screen provided.
