Environment:

    Fedora 27 (up to date)
    Lenovo T460p laptop, 32GB RAM
    various kernels (currently 4.14.22-300)
    XFCE Desktop with lightdm as display manager

Description of problem:

Bringing up emacs and doing any scrolling operations (not paging but line scrolling) causes the X session to crash. 

Journalctl log seems to indicate that an i915 graphics hang may be part of the problem:

Shortly after this emacs dumps core and current session dies, resulting in a login prompt. 

I have not tried with Gnome3, but will try to reproduce there as well.
