Delay after mouse click when using pygame.mouse.get_pos() on macOS

[makorendev]

Environment:

• Operating system: macOS Ventura 13.4.1
• Python version: 3.11.4
• SDL version: 2.26.4
• PyGame version: 2.3.0
• Relevant hardware: Wireless mouse connected through Bluetooth. Doesn't seem to happen when using the built-in trackpad.

Current behavior:

When moving the mouse and clicking at the same time, the value returned from pygame.mouse.get_pos seems to pause for about 10 frames before updating normally again.

Expected behavior:

This function should return an accurate result every frame.

Screenshots

Steps to reproduce:

1. Copy the code below into a blank script and run.
2. Move the mouse around while clicking the left mouse button.
3. Observe the circle pausing for a few frames after each click.

Test code

import pygame
pygame.init()
screen = pygame.display.set_mode((500, 500))

clock = pygame.time.Clock()

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    
    clock.tick(60)
    
    pos = pygame.mouse.get_pos()

    screen.fill("black")
    pygame.draw.circle(screen, "red", pos, 25)
    print(pos)

    pygame.display.flip()

The issue persists with or without clock.tick.
