Wow.

Ah, the dancing bear.

Is that usually visible on the loading screen?

Nope. I think you can see the bear’s shadow occasionally, though.

Ah, never noticed, I wasn’t the one to pay attention to background stuff.

I’ve never seen/noticed the shadow or the bugged menu myself, only these screenshots that pop up now and again. Consider yourself lucky.
