Screen tearing on Macbook Air after Xorg update

So after updating Xorg about a week ago, I have had constant screen tearing going on with my Intel chipset. I can't figure out what the issue is.

I am running Arch on a Macbook Air 5.2 with an Intel 4000 chipset. I am using AwesomeWM and LightDM.

[root@zakalwe xorg.conf.d]# uname -a
Linux zakalwe 3.17.2-1-ARCH #1 SMP PREEMPT Thu Oct 30 20:49:39 CET 2014 x86_64 GNU/Linux

[root@zakalwe xorg.conf.d]# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

Here is the output of "X -version"

	Before reporting problems, check http://wiki.x.org
	to make sure that you have the latest version.

Here is the relevant /etc/X11/xorg.conf.d/ file

Section "Device"
        Identifier  "Intel Options"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
	Option      "TearFree"    "true"
EndSection

Here is an excerpt from my Xorg.0.log file

Any ideas what is causing this/anyone else having the same issue?
Also, let me know if you need me to provide more info.
