The Bug

The world loading animation where is shows the chunk colormap no longer functions properly in 24w19a/b. This is probably due to the changes in chunk loading in 24w19a, as 24w18a has the expected colors in the loading animation.

The chunk colormap only shows the white and light gray colors in the center at 100% loading completion.

How to Reproduce

1. Open a world in 24w18a (or 1.20.6).
2. All the colors display in the loading screen when at 100%, as expected.
3. Now open a world in 24w19b.
4. Note how only the white and light gray colors show, even at 100%.

Additional Notes

This may be intentional.
