I believe I have found the issue, and the patch sent upstream is: http://lists.x.org/archives/xorg-devel/2012-June/031541.html.
I have applied the patch to the package and uploaded a test package to ppa:chasedouglas/jupiter. Please test it out after it has finished building. The version of the package is 2.7.0-0ubuntu1.2~jupiter1. If it resolves the issue, I will create a new SRU package for it.
