--- Comment #5 from Timothy t_arceri@yahoo.com.au --- I'm seeing the issue on Fedora 21 running Mate. I tried yesterday to reproduce under Gnome 3 just in case it was a window manager thing but I couldn't get it to even try to fullscreen but that's a different issue and a gnome one by the looks of things.
