Per-action first-use stutter after joining a world with Vibrant Visuals

After joining a world with “Vibrant Visuals” enabled, the first time I perform certain actions—e.g., scrolling the hotbar, placing/breaking a block, or switching perspective—there is a heavy stutter. Once that specific action has been done, it usually no longer stutters; there are exceptions where it recurs.

Steps to Reproduce:

1. Enable “Vibrant Visuals.”

2. Join any world. (Server, Realm or Local)

3. Perform each action once (scroll hotbar, place a block, break a block, change perspective).
   → The first occurrence of each action typically triggers a stutter.

Expected:

No stutter on initial use of actions after joining a world.

Observed:

Noticeable stutter on the first use of each action post-join; repeats of the same action are usually smooth, with occasional exceptions.
