Why is it when Client joins the camera will have a Rotation Jitter for Basic Character?

When a client joins, his/hers camera jitters like crazy while the servers camera is fine. These are the steps I took:

Create new empty project.
Add new Blueprint GameMode.
Add new Blueprint Character.

In the character:
Add a camera and offset it back( like for a 3rd person game )
Select a skeletal mesh to be used as its Mesh.
Add basic movement code for WASD.
Add basic rotation code using the mouse.

Now start 2 clients, and the client jitter.

Is there something I’m doing wrong, if so how can I get rid of this issue?

Thanks and kind regards,

's an easier repro:

  • Create a new TP_ThirdPersonBP
  • Open MyCharacter, check “Use Controller Rotation Yaw”
  • Make sure you get over 50 fps
  • Set “Run Dedicated Server”, hit play and rotate the character

I suspect this problem comes from APawn::FaceRotation, which ends up in UPrimitiveComponent::MoveComponent.
The jittering only occurs when the character is on the ground.
