I'm using the new i5 6600K on an ASUS Z170-A board (Skylake architecture).
I have connected 2 displays to the integrated GPU, the primary one using DisplayPort, the secondary one using DVI and use the kernel option i915.preliminary_hw_support=1 to get the intel driver do its job.
I boot up, GDM shows fine on both monitors, I login, everything seems ok.
Now when I turn off the primary display, Xorg sets the other display primary and the weirdness begins. For some reason now the image is shifted to the right where the part of the image that "sticks out" gets drawn on the left side. Also, every pixel whose y-coordinate is below the mouse pointer gets drawn in the color of the pixel the mouse is pointing at. Looks like this:

Furthermore, sometimes when I turn the display back on, it gets turned off by Xorg when I move the mouse pointer to the screen and back on again when I move the pointer away from the screen, like it's trying to bully me!
Is anybody experiencing similar problems or has an idea what's going on?
Maybe I should file a bug report, where would that one go?

Update: This seems to be fixed in linux 4.2. I just installed linux-mainline from miffe's repository and got rid of the bug.

I have the exact same problem but have not tried 4.2 kernel yet. I created this bug report: https://bugs.archlinux.org/task/46048
Once 4.2 reaches core repo I'll test again and ask them to close the bug report.
