            Bug ID: 81070
          Assignee: chris at chris-wilson.co.uk
           Summary: Segmentation Fault on screen resize
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: ricardo.funke at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: Driver/intel
           Product: xorg

If I try to change the screen size, I got a segmentation fault from Xorg.

Also, if I try to add a second screen, I got the same segmentation fault from
Xorg.

I use gnome-shell 3.12.2 and when this problem happens, GDM just restarts and
show me the login screen.

Here is the error on journalctl:
