Vibrant Visuals: Severe FPS Drops when world loads and when OS menus open.

With Vibrant Visuals enabled (regardless of graphical settings), severe FPS drops occur in 2 scenarios.

For reference, this has been observed on a single player world without a server or friends present.

• When the world first loads, the FPS drops to 14 for around 10-30 seconds, although this can be attributed to the world loading properly.

• When the Xbox menus are overlayed in any way, such as the Xbox menu, keyboard (when placing signs), the idle screen menu, and any other Xbox OS overlay happens, the FPS drops to 14 and continues for around 10-30 seconds.

How to reproduce.

1. Load a Minecraft world with Vibrant Visuals enabled.

2. Open Xbox OS Menu.

2a. Wait for console idle screen to appear.

2b. Open keyboard through placing signs.

2c. Receive notification (Achievement, message, etc)

Not a game breaking bug by any means, but may cause issues when playing with friends on a server.

Not sure of the Xbox OS, but I am on Xbox Preview build Alpha Skip Ahead.
