I've been seeing this as well (currently testing on Linux Mint Cinnamon)
I have an Asus UX501V Skylake laptop, with secondary display connected
via HDMI.
A little black square with a few pieces of white trash appears in the
top corner of the *current* display (the display where the mouse is),
every time I move the mouse to the other display. It appears and
disappears instantly, as if it is there for one frame only.
Kernel is: 4.8.0-040800-generic
Primary display is Hi-DPI, secondary is 1920x1280
Also, as I type in my console window, the same square appears when I
type. But only on the first key press.
I disabled the Intel driver and am running on the latest 375.10 NVIDIA
driver to see if things would be better, but they aren't.
Will try to update the kernel soon, but having issues with current
builds atm.

Title:
Black flicker when leaving monitor
Status in linux package in Ubuntu:
Triaged
Bug description:
Sometimes, when moving cursor from one monitor to the other, the
external monitor turns black and gets back on again.
The hardware is Dell Latitude E5470 with Docking Station and monitor
connected via DisplayPort (checked both ports and happens on both of
them).
Everything worked correctly on Ubuntu 16.04, but it happens on Ubuntu
16.10. Kernel 4.8.0-25-generic.
The bug isn't related to cursor only, if focus changes by alt+tab it
sometimes happens as well.

bug as this one, but closed.
