Minecraft Realms Java Edition
When loading a new 1.21.5 chunk, breaking a leaf using your hand creates an abundant amount of particle effects. Doesn’t happen when chopping the logs and leaves breaking, but only when using the hand. First noticed when on a camel's back. I had my friend try it at base, and it did not happen, but when they went to a completely new area away from where it was first noticed, it happened.
Environment
Newly loaded chunk, on camel's back (first time), any time of day, forest.
