Memory leak while moving the mouse

[OlaKenji]

Current behavior:

I notised that by monitoring my activity monitor, the memory keeps increasing if I just move the mouse (track pad). I also confirmed that the memory increases by using the psutil module. Below is a code I used. If I keep moving the mouse, the printed value keeps increasing.

Test code

import pygame
import sys
import psutil
process = psutil.Process()

pygame.init()

window_size = (800, 600)
screen = pygame.display.set_mode(window_size)

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill((255, 255, 255))
    
    print(process.memory_info().rss/1000000)  

    pygame.display.update()

pygame.quit()
sys.exit()

Hi, with the latest version pygame-ce, python and windows 11 I can't reproduce the issue, my memory is pretty stable with rare small changes, maybe someone else can reproduce it.
Just in case, I suggest updating your pygame-ce version (latest is 2.5.0) to check if it's already fixed, or maybe even upgrade your python version.

Same here, can't reproduce this with latest pygame-ce, ubunut 22. Please check if this issue persists after upgrading pygame-ce (pip install --upgrade pygame-ce).

I just replicated this issue on a Mac so it is a valid bug. For the record I also tested on Windows 11 and could not replicate it, so perhaps this is specific to Mac.

System: Intel MacBook Pro (2015) running macOS Monterey version 12.7.5
Python version: 3.12.4
Pygame version: pygame-ce 2.5.0

The output started at 81.4 and after running it for a while and moving the mouse it was at 84.6. Oh and to clarify I was using a trackpad too, not sure if it would be any different using a physical mouse.

Marking it as macOS specific.
