Horse, Donkey, and Mule movement is extremely sluggish, delayed, and visually unstable

In the current Preview build, all rideable horses (and donkeys) behave incorrectly.

Movement becomes extremely sluggish, delayed, and visually unstable. This does not happen on the official release.

The bug affects:

• Forward movement

• Turning the camera while riding

• Turning the horse

• Jump timing and responsiveness

• The smooth “forward jump” transition horses normally have

When riding, the horse feels slow, delayed, and laggy, even though the player’s framerate is normal. Jumping has a “late response” and the ascent animation stutters or feels like it’s pausing mid-air. Turning takes much longer than usual, like the horse is reacting at half speed.

This behaviour also affects donkeys.

Steps to Reproduce

1. Launch the latest Bedrock Preview.

2. Spawn or find any horse or donkey.

3. Tame it.

4. Equip a saddle.

5. Attempt to:

   • Move forward

   • Turn left/right

   • Jump

   • Jump while moving forward

6. Compare responsiveness to the latest official Bedrock version.

Observed Result

• Forward movement is slow and delayed.

• Turning takes significantly longer than normal.

• Jumping has input delay and does not feel smooth.

• Jump animation stutters while going upward.

• Combined forward + jump movement feels laggy and broken.

• Donkeys behave the same way.

Expected Results

Horse and donkey riding should behave normally, with smooth forward motion, instant jump responsiveness, and proper turning speed, identical to the official non-Preview build.

Additional Notes

• Issue only occurs in Preview, not in current official release.

• Tested with multiple horses and donkeys.

• Happens even in empty worlds with no structures, no mobs, and default settings.

• Not affected by framerate settings or performance mode.
