dmesg showing the hang

Hey,

Since the upgrade of xorg-server from 1.18.1 (on Arch Linux) to anything newer
I'm experiencing hangs in LibreOffice in KDE/Plasma 5 whenever LibreOffice
opens a popup dialog (e.g. CSV import settings, editing a text style etc.). The
popup dialog is drawn incompletely, the desktop seems to freeze for a couple of
seconds. Often Plasma says it had to restart the graphics stack. If I press ESC
the popup dialog often vanishes after a couple of seconds and I can continue
using the system normally.

Note that popup _menus_ shown by LibreOffice aren't affected, only full
dialogs.

journalctl reports "GPU hang" (see attached journal log file).

Sometimes the X server even crashes completely.

This happens with both xorg-server 1.18.2 and the current 1.18.3. The problem
vanishes as soon as I downgrade xorg-server-* packages back to 1.18.1.

The hang happens regardless of the kernel version used: I had hangs on the old
LTS (4.1.x), Arch's current LTS (4.4.7) and Arch's current normal one (4.5).

LibreOffice is at 5.0.5.

There are several similar bugs with similar driver messages, so feel free to
mark this as a duplicate of the appropriate one.

Steps to reproduce:

- Install KDE/Plasma 5 & LibreOffice on computer with a i915 running Arch Linux
- Start Plasma, start LibreOffice
- Open a dialog in LibreOffice, e.g. by pressing F11, then right-clicking on a
style and chosing "edit" from the popup menu. Observe hang.
