Display "flashing" in "night light" mode since v4.16-rc5

Josef Lechner
Hello dear friends,

I use Arful with newer kernel
(http://kernel.ubuntu.com/~kernel-ppa/mainline). Works fine, but since
v4.16-rc5 (including today's v4.16) screen flashes when in night light
mode, especially when mouse moves. Under kernel v4.16-rc4 works fine.

I am ready to send you any needed information, for now I'm sending
"screenfetch" only...sorry I'm not very experienced.

Best regards, Josef
