I installed this update last week and I have STILL been consistently having the display freeze/flicker/window-drag problems upon coming out of Display Sleep, especially bad when a Thunderbolt device is attached like an external display, hard drive or ethernet adapter. However, it still happens when a Thunderbolt device is not attached.
Also, the other big hitting update in that Software Update list is USB3.0 bug fixes. And, I can confidently say that I still have USB3.0 problems with sporadic drive disconnects while copying large files.
On the bright side, I purchased a Buffalo Thunderbolt External 1TB hard drive from OWC over the weekend and copying large files as well as SuperDuper cloning my entire hard drive (>500GB of data) has gone without a hitch. MUCH BETTER THAN the USB3.0 flakeyness on rMBPs.
So, for those actually keeping their trouble-ridden Retina MBPs, like me, who need to use large external hard drives for backups and extra storage, I HIGHLY RECOMMEND getting a Buffalo Thunderbolt External 1TB Hard Drive from OWC. It's suprisingly affordable in the 200+ range and has been widely reviewed and praised across the internet.
As I said before, the way I have alleviated the display problems upon display sleep resume by configuring my Energy Saver settings to make Display Sleep NEVER.
P.S. Thanks for spreading the news about the Software Update, as it does have specific fixes for display and USB3.0 problems, the most glaring and pervasive glitches with Retina MBPs....however, the software updates have not fixed my display or USB3.0 problems :-)
