I only use my Surface Book i7/16GB/512GB for my work and I've completely eliminated my old desktop. My year old Surface Pro 3 is now my backup computer. I've traded for a living for the past 15 years and I use Interactive Brokers Trader Workstation. I
use Microsoft Office 365 Subscription and I'm an avid amateur photographer using Adobe Lightroom/Photoshop CC Subscription. I was a Microsoft Windows Programmer until 15 years ago and I still like to do some programming using Microsoft Visual Studio 2015.
I use Chrome for the Internet but of course I also have IE and Edge. I've never experienced any flicker on the OS or on any programs on my Surface Book.
The only other thing I might ask about is the Lot # found in the middle of the sticker on the back of your shipping box. Mine is Lot # 1546 and I got mine at the Microsoft Store on November 30th. The earliest Lot # I've seen here on the forum is Lot #
1541. I don't know what the differences might be in Lot numbers but one might guess that later Lot Numbers might have hardware changes.
It is extremely interesting that you are experiencing flicker on two different Surface Books. I buy all my computers from my Atlanta Microsoft Store and if I had your problem I would take them in to the Microsoft Store and show the problem to the Techs
there. I have a lot of confidence in the Techs at my Atlanta Microsoft Store.
That's about everything that I can think of to tell you. I wish you the best in getting your problem resolved.
