Switching to a virtual terminal causes the game to crash or the graphics to render incorrectly. How do I prevent this from happening?

Switching between a virtual terminal (by pressing Ctrl + Alt + F1-F6) and the X server (by pressing Ctrl + Alt + F7) while the game is running may cause the game to crash or the graphics to render incorrectly.

The problem will be fixed the next time you launch the game.

We do not recommend switching to a virtual terminal while running the game, as the problem is likely to occur each time you do so.
