After updating to XFCE 4.12 I can't output a dummy window ( for example like this http://pastebin.com/kV6ctxdV ) using GLEW library from OpenGL
I think the problem related to xfwm4 as if I use another window manager (like openbox or metacity or compiz) it runs normally!!!
My OpenGL version : 3.0
My mesa version : 10.4.6
My GLFW lib version : 3.1-1
