Epic Games Launcher seems to conflict with Visual Studio 2015

Setup:
Windows 10
Visual Studio Community 2015 Update 1
P4VS
Visual Assist
System is a 3 week old OS install. Barely has any software installed.

Story:
I was getting extremely frequent 30sec+ hangs in visual studio when scrolling, changing tabs, clicking menus. Visual Studio would then go grey, completely unusable. I suspected P4VS first because it is usually the problem, then Visual Assist. After removing both plugins the problem persisted. This whole time the Epic Game Launcher was open. Visual Studio went grey screen again and in my “I’m Done For the Night” moment I closed the Launcher. Visual Studio immediately started responding.

Test:
Click around in Visual Studio madly, no hangs.
Open Launcher, click around in Visual Studio, hangs within 2-5 seconds.
Close Launcher, Visual Studio instantly starts responding again.
Repeat a few times while swearing.

In the words of Zoolander, I feel like I’m taking crazy pills.

I can work around this by not keeping the launcher open. I’m curious how this can possibly happen, and secondly, if anyone has had this problem and has a solution. I did some searching in the forums and found no similar issues. I don’t know if Visual Studio is being nosey into running processes or the Launcher is poking Visual Studio.
