The bug

In the "Video Settings" menu, if you try to change your graphics setting to fabulous while using a computer that does not support the fabulous option, you will be shown a warning screen. If you click "Take me back" to exit the warning screen, then when you continue playing in your world translucent blocks will no longer render. Relogging, using F3 + T, or going through a nether portal will cause translucent blocks to render again. Completely transparent blocks such as regular glass render correctly. Also, while this bug is occurring, leaves will render as if the fancy option is selected even if the fast option is selected.

To reproduce

Please see the attached video.
