Enough for me to work:
With open source driver work only vdpau.
With proprietary driver kodi crash on eglInitialize and this will probably never be fixed
I try Nvidia Geforce 1080. And everything works perfectly.
So I will buy a video card nvidia easier
P.S. Sorry for my English
I have the same problem
kodi stable ppa
