  8086:0a26 xorg crashes on Ubuntu 15.10 with Intel graphics

Status in xorg package in Ubuntu:

Bug description:
  Symptom: xorg crashes on windows creation

  How to reproduce: No 100% reproducibility, however intensively using
  2D/3D acceleration triggers the bug (e.g. by opening several new
  windows and/or menus in a Unity desktop environment)

  Affected hardware: Intel HD Graphics 4400/5000 etc
  Affected software:
  - kernel Linux 4.2.0-16-generic #19-Ubuntu SMP x86_64
  - also affected is kernel Linux 4.2.5-040205-generic x86_64
  - Ubuntu 15.10 with Unity (because of compiz 2D/3D acceleration)
  - any other software using direct rendering (e.g. VLC)

  - Disable window animations in Compiz reduces the frequency of the crashes.
  Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager)
  - Use XFCE or LXDE also reduces the frequency of crashes given that these desktop environments are 2D only
