pygame._sdl2.Renderer is broken on my system.

[yolowex]

Environment:

• Operating system:

• OS: Kali GNU/Linux Rolling x86_64
• Kernel: 6.1.0-kali7-amd64

• Python version 3.11.2
• SDL version 2.26.4
• PyGame version 2.2.1
• Relevant hardware

• CPU: 11th Gen Intel i7-11700 (16) @ 4.800GHz
• GPU: Intel RocketLake-S GT1 [UHD Graphics 750]

Current behavior:
_sdl2.renderer is broken on my system.
it says that Renderer is already associated with window

Expected behavior:
I want to render things using _sdl2

Steps to reproduce:

I just copied the code that @Starbuck5 made in discord _sdl2 channel, and pasted it into my problem, running it.

Test code

import pygame
from pygame._sdl2 import Renderer, Texture, Window
import os
here = os.path.abspath(".")+"/"
pygame.init()

screen = pygame.display.set_mode((0,0), flags=pygame.FULLSCREEN)
window = Window.from_display_module()
renderer = Renderer(window)

texture = Texture.from_surface(renderer, pygame.image.load(here+"Capture.PNG"))

print(list(pygame._sdl2.get_drivers()))

clock = pygame.time.Clock()

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

        if event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
            running = False

    renderer.draw_color = (255, 255, 255, 255)
    renderer.clear()

    texture.draw(None, None)

    renderer.present()

    clock.tick()
    print(clock.get_fps(), end="\r")

pygame.quit()

Does pygame.examples.video work?

python -m pygame.examples.video.

[yolowex]

Yes it does.
It opens two windows

[yolowex]

I'll run it from source and start investigating the problem asap.

[yolowex]

I ran it from source and it seems that in pygame.examples.video the window is defined through _sdl2.Window and not
pygame.display.set_mode .
But still, if the code you I earlier posted (which was made by Starbuck) works for other people, the problem has to be related to my OS.
I'll run the snippet in an Emulator to confirm it works in the same conditions that it doesn't in my host os.

[yolowex]

I ran the snippet in an emulated Windows 11 and had no issues.
I can confirm that the pygame-ce and sdl version of both Windows 11 os and Kali linux OS were the same, and the snippet
I mentioned above was run in the exact same conditions in both os's.
the code is not operational in my host os.

I did a bit research(i also had the same error) and renderer = pygame._sdl2.video.Renderer.from_window(window) fixes the issue

UPDATE:I currently builded pygame-ce from source and now the code @mmdmoa provided perfectly works.So i think updating pygame-ce may solve the issue.

Nope, for me using dev3 didn't solve the problem.

but replacing the code you provided with the recent one fixed my issue.

@Starbuck5
regarding to this event, do you think it's possible that the problem is not with SDL itself?

[Starbuck5]

It's not like pygame-ce was creating a renderer for no reason before, and isn't.

cool-guy says that updating to dev3 fixed the issue, I'm very confident building from source is what actually fixed the issue.

My theory is that newer SDL (newer than your system SDL), creates a renderer in the backend when you get a display surface from a SDL_Window, and that explains the problem. So I think the problem is with SDL itself.

[yolowex]

@cool-dev-guy
can you tell me what version of SDL are you using?
for me it's this:

pygame-ce 2.3.0.dev3 (SDL 2.26.5, Python 3.11.2)

[Starbuck5]

@yolowex Test this.

#include <stdio.h>

#define SDL_MAIN_HANDLED

#include "SDL.h"

// my compile command
// gcc test.c -ISDL2 -lsdl2 -L.

#define SDL_ERROR                            \
    printf("SDL error: %s", SDL_GetError()); \
    exit(1);

int main()
{
    SDL_Init(SDL_INIT_EVERYTHING);

    SDL_Window *win = SDL_CreateWindow("test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 500, 500, 0);
    if (!win)
    {
        SDL_ERROR
    }

    SDL_Surface *screen = SDL_GetWindowSurface(win);
    if (!screen)
    {
        SDL_ERROR
    }

    SDL_Renderer *renderer = SDL_GetRenderer(win);
    printf("renderer = %p\n", renderer);

    SDL_Quit();

    printf("Finished.\n");
}

Getting the renderer from your window should be NULL, since a renderer was never created. However I think on your system it will not be NULL.

[yolowex]

When I run it, I get this:

└─$ ./main
renderer = 0x5648f705f330
Finished.

this is a bad thing right?

Edit:
could it be that some program in my OS has created an sdl renderer, so it's always occupied?

[yolowex]

a contributor of SDL added a pr that probably solves this problem, but I have no Idea how to compile SDL from source to test if the issue is resolved.
