SDL_MinimizeWindow OSX Problem

Hi,

does anyone here also has problems with minimizing a fullscreen window (gl
context) on OSX? I have a visit-my-homepage-button in my game that
minimizes the window, and opens a url - this works perfectly on android,
windows, linux - but not on osx. The screen stays black - and the game
doesn’t respond anymore for a random time. Even the mouse input seems to be
broken after it recovered (wrong coordinates). The code is here:

}


void SDLFrontend::disableScissor ()
{
	SDL_assert(_renderer);
	SDL_RenderSetClipRect(_renderer, nullptr);
}


void SDLFrontend::onWindowRestore ()
{
#if __APPLE__
	Log::info(LOG_COMMON, "restored");
	const ConfigVarPtr& var = Config.getConfigVar("fullscreen");
	setFullscreen(var->getBoolValue());
#endif
}


void SDLFrontend::minimize ()
{
#ifdef __APPLE__
	SDL_SetWindowFullscreen(_window, SDL_FALSE);

	IFrontend *_frontend;
	bool _newWindow;
public:
	OpenURLListener (IFrontend *frontend, const std::string& url, bool newWindow = true) :
			_url(url), _frontend(frontend), _newWindow(newWindow)
	{
	}


	void onClick () override
	{
		_frontend->minimize();
		System.openURL(_url, _newWindow);
	}
};


#ifdef __EMSCRIPTEN__
	class EmscriptenFullscreenListener: public UINodeListener {
	public:
		void onClick () {
			EM_ASM({
				Module.requestFullScreen();

#include <CoreServices/CoreServices.h>


Darwin::Darwin () :
		Unix()
{
	darwinInit();
}


Darwin::~Darwin ()
{
}


int Darwin::openURL (const std::string& url, bool) const
{
	CFURLRef cfurl = CFURLCreateWithBytes(nullptr, (const uint8_t *) url.c_str(),
			url.length(), kCFStringEncodingUTF8, nullptr);


	const bool success = LSOpenCFURLRef(cfurl, nullptr) == noErr;
	CFRelease(cfurl);
	return success ? 0 : -1;
}

Thanks for your help.–
