DirectX Fatal Error 11000002 Since 3.4 Patch

http://imgur.com/ByN1LVX.png

So this has been going on for a month and a half ever since patch 3.4 dropped. It only happens when I run two clients simultaneously. Before patch 3.4 I could run two clients simultaneously without issue. I have no upgraded my PC since July of last year so it's not my system specs.

I have tried numerous apparent fixes and even looked into the old thread about this issue that happened to people late the year before last into the early parts of January the next year. None of the fixes in that thread have helped so far.

I am at a complete loss and I'm beginning to think this error is client side as I've said before this issue only started happening right after the 3.4 patch.

But here is my display driver just in case.
Display Driver: NVIDIA GeForce GTX960
Driver Hardware Version: 375.70
NVIDIA GeForce Experience Version: 3.1.0.52

As stated above I've tried every fix recommended for this error from disabelling NVIDIA GeForce Experience while playing to changing values in the Regedit. I am at a total loss as to what could be the problem.

I'd also like to add that this only happens to the client I have that's in "Inactive" mode where I'm alt tabbed to either the other client or I'm browsing the web.

Ok this is now starting to happen even when I have one client up; so long as I'm alt tabbed it happens.

This has been happening to me for a while too. I did a complete wipe on my computer and reinstalled as well. Have you had any luck with this? It is becoming extremely frustrating.

This is how I fixed it on mine, when all else failed...

Yeah I tried this and it didn't work. This error only seems to work on DirectX 11 versions. DirectX 9 is fine. But this is in no way a solution to the problem.
