Title:
  8086:0116 [i915] Screen display corruption resizing LibreOffice Calc
  window Acer Aspire 5750-9668

Status in X.org xf86-video-intel:
  Invalid
Status in “libreoffice” package in Ubuntu:
  Confirmed
Status in “xfwm4” package in Ubuntu:
  Confirmed
Status in “xserver-xorg-video-intel” package in Ubuntu:
  Invalid

Bug description:
  1) lsb_release -rd
  Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04

  2) apt-cache policy xserver-xorg-video-intel Installed: 2:2.99.910-0ubuntu1
  apt-cache policy libreoffice-calc Installed: 1:4.2.3~rc2-0ubuntu1

  3) What is expected to happen in a blank Calc document is when one
  resizes the window, it does not have screen display corruptions.

  4) What happens is it does as per attached screenshot
  https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
  intel/+bug/871972/+attachment/2535351/+files/screenshot.png .
  Following https://wiki.ubuntu.com/Backtrace please see
  https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
  intel/+bug/871972/+attachment/2535349/+files/gdb-libreoffice.txt for
  backtrace information.

  Toggling Settings -> Window Manager Tweaks -> Compositor -> Enable
  display compositing checkbox made no difference.

  As well, this would appear to have never been a UXA bug as I'm currently using SNA and it's still reproducible verbatim:
  grep "SNA init" /var/log/Xorg.0.log
  [     6.059] (II) intel(0): SNA initialized with Sandybridge (gen6, gt2) backend

  The problem has been reproducible since:
  1) lsb_release -rd Description:	Ubuntu 11.10 Release:	11.10
  apt-cache policy xserver-xorg-video-intel Installed: 2:2.15.901-1ubuntu2
  apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.4.3-3ubuntu2

  This was not reproducible in a Natty 11.04 live CD, so this may be a regression:
  xserver-xorg-video-intel 2:2.14.0-4ubuntu7

  This is not reproducible in GNOME Flashback (Metacity). However, this
  would not quite be a WORKAROUND as it has bugs when utilizing the
  touchpad, preventing me from switching to it from XFCE.

  WORKAROUND: The screen display corruptions are reversed maximizing,
  and then restoring the window.
