Is it normal for the screen to go black when I am backing-up to a flash drive?

Is it normal for the screen to go black when I am backing-up to a flash drive? It doesn't happen every time, but most often.

Let's just say that it isn't "uncommon".  Because of the way they did the main screen, if it gets busy doing something like backing up, the screen isn't refreshed and as a result is black.
