Comment 25 for bug 981168

@Jay, I can confirm that patching unity with your change seems to resolve the problem.

USC reloads or flashes and seems to lose its position, so perhaps something is still imperfect, but the visual corruption is gone, and programs seem to install successfully.

Jay, I can't tell in reviewing your patch if it's a true fix or a workaround. Is there any actual kernel or X.org changes needed for this issue, or is your unity fix going to be considered the solution? If more is needed on the X or kernel side, please reopen the X task and let us know more specifically whats needed. (A minimal testcase we could pass to upstream would be ideal.)
