and
xserver-xorg-video-amdgpu 1.0.99+git1511200733.43c2dc~gd~w

glxgears and smoother desktop at startup.
But I still have
1) mouse freezes when starting steam
2) if I run Unigine Heaven

I don't even get 60 fps in glxgears with a tiny window:
292 frames in 5.0 seconds = 58.264 FPS
286 frames in 5.0 seconds = 57.198 FPS
291 frames in 5.0 seconds = 58.198 FPS
