MacOS - open native file dialog when in full screen mode goes haywire

[jawaidbazyar2]

I enter full screen mode on MacOS like so:

if (display_fullscreen_mode == DISPLAY_FULLSCREEN_MODE) { SDL_DisplayMode *selected_mode;

    SDL_DisplayID did = SDL_GetDisplayForWindow(window);
    int num_modes;
    SDL_DisplayMode **modes = SDL_GetFullscreenDisplayModes(did, &num_modes);
    for (int i = 0; i < num_modes; i++) {
        printf("Mode %d: %dx%d\n", i, modes[i]->w, modes[i]->h);
    }
    selected_mode = modes[0];

    SDL_SetWindowAspectRatio(window, 0.0f, 0.0f);
    SDL_SetWindowFullscreenMode(window, selected_mode);
    SDL_SetWindowFullscreen(window, display_fullscreen_mode);
    SDL_free(modes);

}

then if I attempt to open native file dialog like so: SDL_ShowOpenFileDialog(file_dialog_callback, userdata, osd->get_window(), filters, sizeof(filters)/sizeof(SDL_DialogFileFilter), nullptr, false);

a strange series of events occurs: window shrinks then zooms back up to full size then shrinks again

The open file dialog is nowhere to be seen. The state of the application window is confused.

This code works as expected when the window is in window mode, instead of full screen mode.

If instead of modes[0] selected_mode, I pass NULL to SetWindowFullScreenMode, the open file dialog works as expected. (But the full-sizing process is really slow when using NULL, so I prefer passing the selected fullscreen mode if it can be achieved.
