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.


Steps to reproduce:
Install mesa-17.1.8xxx everything works fine
Install mesa-18.2

Here is a journalctl from a good boot with Mesa-17.1.8

Here is a bad boot with Mesa 17.2

Same thing happens here, some of the letters are faded or close together, looking garbled, there is nothing in my journalctl or xorg logs though.

Also wanted to point out. I'm using the intel driver, no nvidia driver and nouveau is black listed.

I figured out how to reproduce this bug on my laptop. I've got a TB16 connected to my XPS. I run two external 4k monitors. Running on Mesa-17.2x with just the laptop display, or only one external 4k monitor works great. Immediately after connecting the 3rd 4k monitor, the drawing issues start. From the look of it, I'd say there's a memory buffer which is overflowing with > 2 4k displays.

Few things to try:
1) is Mesa 17.3.x in the same state?
2) use the modesetting (instead of intel) driver - see https://wiki.archlinux.org/index.php/Intel_graphics
3) establish a [as trivial as possible] way to reproduce and open an upstream report - see https://01.org/linuxgraphics/documentation/how-report-bugs
