seekrs / macrolibx Goto Github PK

We noticed that the use of RAM only increases until the PC freezes. It gets faster and faster if you put pixels in the image. We noticed this in the function below called in a loop with mlx_loop_hook()

void	function(t_mlx *mlx)
{
	if (mlx->img)
		mlx_destroy_image(mlx->mlx, mlx->img);
	mlx->img = mlx_new_image(mlx->mlx, WIDTH, HEIGHT);
	mlx_put_image_to_window(mlx->mlx, mlx->win, mlx->img, 0, 0);
}

Here's an issue to propose and discuss ways to reduce or eliminate leaks from SDL2 and Nvidia. If anyone has any idea he/she will be pleased to share it here !

Sometimes a conditional jump can be reported by valgrind on image destruction

seems to be coming from https://github.com/seekrs/MacroLibX/blob/master/src/renderer/descriptors/vk_descriptor_set.cpp#L122

When setting the fps goal to a value lower than the maximum fps, the macrolibx will sometimes uncap the fps briefly, either randomly or after lagging (eg using valgrind or mashing the refresh key on fdf)

random spike

mashing refresh on fdf

#include <mlx.h>

int main()
{
    void* mlx = mlx_init();
    mlx_destroy_display(mlx);

    mlx = mlx_init(); // crash with SDL_Init
    mlx_destroy_display(mlx);

    return 0;
}

wtf

gives :

but this :

gives this :

[MacroLibX] Error : Graphics allocator : some MLX-dependant allocations were not freed before destroying the display (2644 active allocations), please report, this should not happen

I can't figure out how to use multiple fonts on one image/frame on rendering, I don't know if that's supposed to be possible, and if not I think it'd be a great addition. In any case, great, clean and fast code !

e.g:

int	my_loop(t_mlx *mlx)
{
	mlx_set_font(mlx->mlx, mlx->win, "font1.ttf");
	mlx_string_put(mlx->mlx, mlx->win, 200, 50, 0xFF00FFFF, "Hello im font1");
	mlx_set_font(mlx->mlx, mlx->win, "font2.ttf");
	mlx_string_put(mlx->mlx, mlx->win, 200, 100, 0xFF00FFFF, "Hi font1, im font2");
	return (0);
}
