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 didnīt 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. > I'll update to newer rc and see if it happens again, but if you have > any ideas, now would be good time. No ideas, sorry.
