Vibrant Visuals automatically disables when second player joins in split-screen on Xbox Series X

Steps to Reproduce:

1. Launch Minecraft Bedrock on Xbox Series X.

2. From the main menu, start a new world or enter an existing world.

3. Observe that Vibrant Visuals is active by default.

4. Have a second player join the session using split-screen.

Expected Result:

Vibrant Visuals should stay active when playing in split-screen mode.

Actual Result:

As soon as the second player joins using split-screen, Vibrant Visuals disables automatically for both players.

Additional Notes:

• No resource packs or addons were in use.

• Playing on Minecraft Bedrock 1.21, “Chase the Skies” update.

• Console: Xbox Series X.

• The setting “Allow In-Game Graphics Mode Switching” was enabled, but there is no manual toggle for Vibrant Visuals — it is active automatically when supported.

This issue affects the experience when playing locally with multiple players and should be investigated.
