And it has created a really irritating problem for me. I play Assassin's Creed Syndicate that activates a UPlay account. I use a PS4 controller connected to the computer with a power cord USB connector. I also have a Steam account for playing Obduction. Now when I play Syndicate every time I press L3 to activate eagle vision if opens some kind of on screen keyboard thing that is associated with Steam Big Picture. When I press the O button to close the keyboard it minimizes my Syndicate game to the taskbar and opens the Steam program. Even if I don't have any programs open I can plug in the PS4 controller, press L3 and it brings up the on screen keyboard thing. I haven't found a way to disable the controller in Steam and I may just have to uninstall Steam.
