Hello, Okay for me the problem was indeed that I had 64bits librairies. After recompiling them for 32bits it worked fine. Also when I use any of Esteban's examples even after I close the window I still have a SDL2 event loop processs active in the process browser. And sometimes (but i have not been able to reproduce it everytime) I have an Oswindow renderer loop staying active too.
