display.set_mode memory leak with SCALED flag

[MightyJosip]

While testing some stuff, I noticed that there is a memory leak in display.set_mode, but only in specific conditions. To be exact, when the function calls PG_CreateSurface. It is called for example, when you pass SCALED flag. Looks like that surface is later not deleted. It can be shown with the following code

import pygame
import psutil
import os
while True:
    pygame.display.set_mode((800, 600), flags=pygame.SCALED)
    print(f"Memory usage: {psutil.Process(os.getpid()).memory_info().rss / 1024 / 1024:.2f} MB")

It uses the psutil, which has to be pip installed, but you can notice it with

import pygame
while True:
    pygame.display.set_mode((800, 600), flags=pygame.SCALED)

And looking at the Windows Task Manager, or whatever alternative for your OS

No memory leak for me on Ubuntu 25.04 and standard pygame-ce 2.5.5 release install

No memory leak for me either. Arch/GNOME with pygame-ce 2.5.5.
