I'm having this same issue on a Dell 7537 running Ubuntu 16.10 (kernel
4.8).
The flickering that occurs is a rapid change in the brightness of the screen,
in a random, persistently manner (it never stops).
Not so often the screen goes all white and quickly returns to normal.
It's interesting to mention that on Ubuntu 16.04 (kernel 4.4) the bug
appears to be fixed, as the flickering does not occur.

Title:
Screen flickering in Intel i915 driver
Status in Nouveau Xorg driver:

Bug description:
There's an upstream bug reported here
https://bugs.freedesktop.org/show_bug.cgi?id=91393 that causes screen
flickering when using the Intel i915 builtin driver (at resolutions
lower than the maximal one).
I think that it will be fixed in newer kernel versions, but for the
time being, as reported here
https://bugs.freedesktop.org/show_bug.cgi?id=91393#c25 (and as
personally tested) reverting those two commits fixes the problem.
Would that be possible to release a fixed version for the 4.2.0
stream?
