Since Mesa 1.7.2-xxx was released, running more than 2 total 4k monitors (laptop, and 2 external monitors) my display on gnome3 goes crazy.
Pictures of the drawing issue when running more than 2 4k monitors:

Running mesa 17.1.8 everything is fine
Additional info:
* mesa-17.2-x
* GDM and Gnome 3 running X
* Dell XPS 15 9650 (Early 2017)
* Desktop is responsive, but drawing is incorrect.
* Running pure intel, no bumblebee/nvidia
* nouveau is blacklisted
Here is a journalctl from a good boot with Mesa-17.1.8

Is there anyone out there with an: XPS 15 9650, access to a TB-16 and 2 external 4k monitors that can try out their system and let me know if it works for them?
Thanks all
