I can confirm that the blank screen flickering is gone with
4.6.0-997-generic intel-drm-next.
I could try to bisect https://git.launchpad.net/~ubuntu-kernel-
test/ubuntu/+source/linux/+git/mainline-crack ,which is the base for the
4.6.0-997-generic intel-drm-next. A quick search suggests a list of 4-5
possible commits.
Should this be done? Bisecting is very tedious.

I am on a Dell XPS 13 9350 FullHD and I do have the Flicker under Kernel
4.4.0-18 on Ubuntu 16.04 LTS.
I am a bit lost in all these comments, could someone tell me what patch
I can try to see if one of your patches has affect on my setup?
There is also a Bug report related to this one over here:

I am currently bisecting the kernel again and one thing I realize is
that I can detect an error through dmesg and then set the commit to bad,
but after reviewing some kernels which I have marked as good, it turns
out these were bad too. This messed up my bisect and I have to start
over again.

@ Richard Platt
Are you still without flicker? If so, what Kernel are you on? (uname -a)
