Was on Leap 42.2 and after doing weekly update, my xbox 360 controller not working anymore on any games except in big picture menu (same things happen with steam link) ... In settings, xbox is well recognize as this pad.
So as Nvidia publish nvidia driver on Tumbleweed, I've upgrade my computer to rolling release to see if it's same things. And it does ... The only difference is that now steam is working like a charm without have to launch in command line with : STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 steam

Any idea of what it could happen ? kernel problem ? xbox 360 driver are in it ? isn't it ?

It could be due to Steam ? https://steamcommunity.com/app/207140
