Describe the bug
mlx_put_pixel isn't putting pixels on image

To Reproduce

1. copy the code from the README.md (or below) to a .c file.

#include <stdio.h>

int32_t ft_pixel(int32_t r, int32_t g, int32_t b, int32_t a)
{
    return (r << 24 | g << 16 | b << 8 | a);
}

void ft_randomize(void* param)
{
	for (int32_t i = 0; i < image->width; ++i)
	{
		for (int32_t y = 0; y < image->height; ++y)
		{
			uint32_t color = ft_pixel(
				rand() % 0xFF, // R
				rand() % 0xFF, // G
				rand() % 0xFF, // B
				rand() % 0xFF  // A
			);
			mlx_put_pixel(image, i, y, color);
		}
	}
}

void ft_hook(void* param)
{
	mlx_t* mlx = param;

	if (mlx_is_key_down(mlx, MLX_KEY_ESCAPE))
		mlx_close_window(mlx);
	if (mlx_is_key_down(mlx, MLX_KEY_UP))
		image->instances[0].y -= 5;
	if (mlx_is_key_down(mlx, MLX_KEY_DOWN))
		image->instances[0].y += 5;
	if (mlx_is_key_down(mlx, MLX_KEY_LEFT))
		image->instances[0].x -= 5;
	if (mlx_is_key_down(mlx, MLX_KEY_RIGHT))
		image->instances[0].x += 5;
}

// -----------------------------------------------------------------------------

int32_t main(int32_t argc, const char* argv[])
{
	mlx_t* mlx;

	// Gotta error check this stuff
	if (!(mlx = mlx_init(WIDTH, HEIGHT, "MLX42", true)))
	{
		puts(mlx_strerror(mlx_errno));
		return(EXIT_FAILURE);
	}
	if (!(image = mlx_new_image(mlx, 128, 128)))
	{
		mlx_close_window(mlx);
		puts(mlx_strerror(mlx_errno));
		return(EXIT_FAILURE);
	}
	if (mlx_image_to_window(mlx, image, 0, 0) == -1)
	{
		mlx_close_window(mlx);
		puts(mlx_strerror(mlx_errno));
		return(EXIT_FAILURE);
	}
	
	mlx_loop_hook(mlx, ft_randomize, mlx);
	mlx_loop_hook(mlx, ft_hook, mlx);

	mlx_loop(mlx);
	mlx_terminate(mlx);
	return (EXIT_SUCCESS);
}

2. compile it.
3. run.

Expected behavior
It should make a square with random colors just like a static TV.

Additional context
The MLX from France works fine, but I'm doing my project (cub3D) with this one because is faster and better

lol? That’s interesting? I’ll try and see if I can replicate it.

So I downloaded a game in Steam and thanks to that game I discover that my GPU (Intel UHD Graphics) driver was like 0.0.1.4012 versions behind the most recent version, what is weird because I have a software to detect and update drivers and the Intel DSA that does the same, but both didn't detect that the GPU was old, after updating it was rendering OK.
So i will close this issue since the problem was related to drivers.

ps. Sorry for making you was time searching for a solution.
