Find a bug when SDL_WINDOWEVENT_MINIMIZED the gpu flash is overflow.

[superowner]

I just set if (e.window.event == SDL_WINDOWEVENT_MINIMIZED) { cef_renderer_flag = false; } else if (e.window.event == SDL_WINDOWEVENT_RESTORED) { cef_renderer_flag = true; }... ...

   if (!cef_renderer_flag)
    {
        SDL_Delay(100);
        continue;
    }

then it's OK!
