When main monitor is powered off / powered on, then Assertion failure in WIN_AddDisplay

[remss]

I have a setup with 2 monitors. Here the repro steps:

• I open my application and place the SDL Window on the screen 1 (the main screen).
• When I power-off the main screen 1 then the window moves to the screen 2.
• When I power-on the screen 1 then the window returns to the screen 1 but an assert is hit because index is 2 and display_index is 0:

Assertion failure at WIN_AddDisplay (sdl2-src\src\video\windows\SDL_windowsmodes.c:380), triggered 1 time:
  'index == *display_index'

Note that in Release there is no crash at all, just this assert hit in Debug mode.

Here a simple main.cpp to reproduce:

#include <SDL2/SDL.h>
#include <iostream>

int main(int, char **)
{
    if (SDL_Init(SDL_INIT_VIDEO) != 0)
    {
        std::cerr << "SDL_Init Error: " << SDL_GetError() << std::endl;
        return 1;
    }

    SDL_Window *window =
        SDL_CreateWindow("SDL2 Window", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN);
    if (window == nullptr)
    {
        std::cerr << "SDL_CreateWindow Error: " << SDL_GetError() << std::endl;
        SDL_Quit();
        return 1;
    }

    SDL_Renderer *renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
    if (renderer == nullptr)
    {
        std::cerr << "SDL_CreateRenderer Error: " << SDL_GetError() << std::endl;
        SDL_DestroyWindow(window);
        SDL_Quit();
        return 1;
    }

    bool quit = false;
    SDL_Event e;
    while (!quit)
    {
        while (SDL_PollEvent(&e) != 0)
        {
            if (e.type == SDL_QUIT)
            {
                quit = true;
            }
        }
        SDL_SetRenderDrawColor(renderer, 0xFF, 0xFF, 0xFF, 0xFF);
        SDL_RenderClear(renderer);
        SDL_RenderPresent(renderer);
    }

    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}
