Description Ioannis Makris 2017-09-12 01:08:39 UTC 
I think that SDL_SetWindowPosition, on Windows, would never send a SDL_WINDOWEVENT_MOVED

in SDL_video.c (https://hg.libsdl.org/SDL/file/d167d43d74f2/src/video/SDL_video.c) we have the following:

  1813         if (!SDL_WINDOWPOS_ISUNDEFINED(x)) {
  1814             window->x = x;
  1815         }
  1816         if (!SDL_WINDOWPOS_ISUNDEFINED(y)) {
  1817             window->y = y;
  1818         }
  1819 
  1820         if (_this->SetWindowPosition) {
  1821             _this->SetWindowPosition(_this, window);
  1822         }
  1823         SDL_SendWindowEvent(window, SDL_WINDOWEVENT_MOVED, x, y);

then in SDL_windowevents.c (https://hg.libsdl.org/SDL/file/d167d43d74f2/src/events/SDL_windowevents.c):
  
https://hg.libsdl.org/SDL/file/d167d43d74f2/src/events/SDL_windowevents.c

   122         if (data1 == window->x && data2 == window->y) {
   123             return 0;
   124         }
   
but data1 and data2 is x and y. It will always return 0 and skip sending the message further.
