Collision Between Two KinematicBody2D

In my scene I have two characters using KinematicBody2D for movement that are controlled via user input. The problem is that when the two characters move at each other and collide, instead of stopping they seem to jitter for a few seconds first. I’ve tried using move_and_collide and move_and_slide but neither method seems to change this.

extends KinematicBody2D

export var player = 1
export var walk_speed = 3.0
var velocity = Vector2.ZERO

func _ready():
	#Set up collision layers/masks depending on player 1/2.
	if player == 1:
		self.set_collision_layer_bit(0, true)
		self.set_collision_mask_bit(3, true)
	elif player == 2:
		self.set_collision_layer_bit(3, true)
		self.set_collision_mask_bit(0, true)

func _physics_process(delta):
	#Horizontal Motion
	var input_h = Input.get_action_strength("p%s_right" % player) - Input.get_action_strength("p%s_left" % player)
	velocity.x = input_h * walk_speed
	var collision = move_and_collide(velocity * delta)

When 2 kinematic bodies interact this can happen.
Try switching to rigidbody, it has an handy property called mode: you can keep the players in kinematic mode to make them behave as a normal kinematic body, and change them to rigid when a player-player collision is detected.
