Hello,
I've switched to fedora 22 with the Gnome 3.16.2 desktop enviroment and I noticed that the OS is reporting after 5seconds that my SFML application is not responding anymore, however the app just runs fine when I press "wait".
I tried the lastest release and the current master both produces the same behaviour. I used the "gcc (GCC) 5.1.1 20150618 (Red Hat 5.1.1-4)" to compile SFML. Tell me when I should provide more informations about my systems, could this be related with the xcb change?
Edit1: I'm using the default SFML Window code (So yes, I have a pollEvent loop)
