Textures get corrupted for a moment when turning fancy graphics on/off

What I expected to happen was that the game would switch to fancy graphics instantaneously without issue.

What actually happened was that the graphics got corrupted for a moment.

Steps to reproduce:

1. Go into any world
2. Open the pause menu with plus ( )
3. Go into settings
4. Scroll down to “Video”
5. Tap the fancy graphics button.
