Bug Description
I have a HP Spectre x360 laptop with i7-6500U and HD Graphics 520, running Linux Mint 18 MATE x86_64.
Right after X launches rendering, screen starts to produce glitches, flickering, artifacts and blinking both on framebuffer and X.
I've made a short video that demonstrates this exact behaviour: https:/
I have tried using other kernels from PPA mainline, including "intel drm nightly", without success.
Kernels I tried exactly: 4.4.0-21, 4.5.0, 4.6.0, 4.6.2, 4.7.0-994, 4.8.0-994 (intel drm nightly)
I have also tried Debian Stretch (4.6.0-1), Slackware 14.2 (4.4.x), Arch 2016.08.01 (4.6.4.1).
All these distros show exactly the same behaviour.
It happens using both UEFI and Legacy boot modes.
I am including dmesg, Xorg.log and lspci -c outputs using all these kernels in this report.
Important note that it only happens using 4.x kernels. I've just tried Ubuntu 14.04.3 with 3.19.0-25 kernel, it runs fine without any issue.

I thought that it's worth including logs of a working Ubuntu 14.04.3 running 3.19.0-25 kernel for further comparisson, because there are completely no issues using this kernel.
