I have seen this in 4.8 up to rc5 as well. I am not sure yet about rc6 which I 
am currently running.

I didn´t run xrandr by hand. But I ran systemsettings, dragged the second, 
deactivated external display back beneath the internal laptop display, 
activated it again and applied this changes. I think this has a somewhat 
similar effect as Plasma uses RANDR as well.

No ideas, sorry.
