Launch the game from the console while this component is running. I've checked with myself, and the showing, animation, and disappearing all work as expected. There are no lessons at the moment, but I am in the process of creating them.
Got it. Also, is there a way to remove the white margins on either side of the game? Changing the size, resolution settings, or image centering doesn't seem to work. Even windowed, there's always a little gap of white.
This is a bug, I'm still looking for a way to fix it. However, it can be temporarily removed if you set "Maintain Proportions" in the display settings.
