Loading Terrain has a delay when changing dimensions or respawning

The Loading Terrain screen that pops up when joining a world, changing dimensions, or respawning, used to be almost instant in the recent versions of Minecraft. As of 25w31a however, there seems to be an arbitrary delay when changing dimensions or respawning. About 0.8 milliseconds or so. Joining a world in 25w31a is much faster than 1.21.8 however.

I am using the same hardware on both versions, same java version, same launcher, same settings, on a vanilla client.

Steps to Reproduce:

1. Load into a singleplayer world in 25w31a

2. Travel to the nether or respawn after dying anywhere in the world

3. Pay attention to how long Loading Terrain is on screen for

Expected Result:

Dependent on hardware, the loading terrain screen would be nearly instant when respawning or changing dimensions.

Actual Result:

The loading terrain screen has a ~0.8 millisecond delay
