Xorg log on a GLK NUC that cannot reproduce the issue

I tried to reproduce the issue, to no avail:

HW:
 - GLK NUC (J4005) with one or two sticks of RAM
 - 2 HDMI screens, one 4K (rotated) and a full HD one

SW:
 - Linux 4.16-rc7
 - X-server 1.19.6
 - Intel DDX / SNA: 2:2.99.917+git20171229-1
 - DRI2 and DRI3 got tested

First of all, are you sure you are using DRI2? I added code to mesa a long time
ago to be able to distinguish between the two: LIBGL_DEBUG=verbose glxgears.

Have you tried running a compositor instead of running on a bare-bone X? You
can try compton which is a standalone X11 compositor.

Hope this helps.
