Question about software renderer and window surface

SDL Development
1

Hello,

Recently there was a renderer change Make it clear that you can't mix 2D rendering and the window surface API · libsdl-org/SDL@36033e3 · GitHub which seemed to make renderer creation fail in case software renderer was created earlier. I wonder now should this be fixed on application side by checking and destroying potential window surface, or should SDL_DestroyRenderer remove window surface as well?

Example code (tested on Linux Mint 64-bit). It should print:

Failed to create 2nd renderer: Surface already associated with window

#include <SDL.h>

int main()
{
	if (SDL_Init(SDL_INIT_VIDEO) == 0) {
		SDL_Window* w = SDL_CreateWindow("test", 100, 100, 100, 100, 0);
		if (w) {
			SDL_Renderer* r = SDL_CreateRenderer(w, -1, SDL_RENDERER_SOFTWARE);
	
			if (r) {
				SDL_DestroyRenderer(r);

				//SDL_DestroyWindowSurface(w); 

				r = SDL_CreateRenderer(w, -1, 0);

				if (r) {
					printf("Created both renderers\n");
				} else {
					printf("Failed to create 2nd renderer: %s\n", SDL_GetError());
				}

				SDL_DestroyRenderer(r);			
			} else {
				printf("Failed to create 1st renderer: %s\n", SDL_GetError());
			}

			SDL_DestroyWindow(w);
		}

		SDL_Quit();
	}
	return 0;
}
