I'm seeing this on Trusty, on an HP Z420 and an HP Z620, both with
nVidia cards.
It occurs primarily when transitioning between workspaces. I've found
that I can (mostly) work around it by always transitioning first to a
blank workspace (one with no windows, just the background image), and
then to the workspace I wanted. Moving directly from one workspace with
windows to another with windows triggers corruption most of the time.

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

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.
