[Big Box] Graphical Glitch When Exiting Retroarch

When I have BB set to use the Loading message and I begin a game in Retroarch, if at any point during the gameplay I access the Retroarch menu, exiting the emulator will return me to a screen that looks like this, where the Loading message remains partially visible. This happens no matter what theme I’m using.

The partially displayed Loading message will vanish as soon as I navigate to another game.
