screen corruption example
Hi all.
I've got a Dell XPS 15 9560 running Archlinux with kernel 4.13.11.
I'm using Cinnamon desktop 3.4.6, xorg-server 1.19.5.
The laptop has Nvidia GeForce GTX 1050 (4GB GDDR5); Intel HD Graphics 630.
The intel card is set up with KMS, I don't have xf86-video-intel installed.
I'm trying to use a Dell TB16 dock with two LG 27UD58-B 27" UHD 4K monitors and
a built-in screen. Screens are connected through displayport cables to the TB16
dock.
(Intel(R) Core(TM) i7-7700HQ)
Screens work fine in mirror mode, but as soon as I set the displays to be
horizontally aligned next to eachother, screen corrupts. It works fine if one
of the screens is positioned below the other two.</pre>
