"Alt +1" screenshots are partially blackened on XO-4 on build 30

Please see the attached screenshot of the 'blackened' screenshot.

Other notes ::
=============

a)
Things worked fine on build 21 for XO-4.

b)
Things always work fine for other platforms (tested on XO-1.75) for build 21 AND build 30.

c)
If xorg-x11-drv-dove is upgraded from 0.3.5-7 to 0.3.5-8 on build 21 of XO-4, the issue starts happening on build 21 too.

d)
If xorg-x11-drv-dove is downgraded from 0.3.5-8 to 0.3.5-7 on build 30 of XO-4, sugar fails to boot.

All in all, xorg-x11-drv-dove (version 8) is the culprit; however, downgrading it to version-7 causes the XO-4 to do not boot.
