Blueprint icon flashes when hovered over

Blueprint icon flashes constantly when mouse is hovering over it; this only occurs with a specific type of blueprint class.

. Branch: Binary, from Launcher
. Build Version: 4.7.3
. Description: This happens when I hover my mouse over the blueprint icon. The blueprint is derived from a C++ base class, AHUD, containing 1 static mesh component and 1 material.

I have not been able to reproduce this on my system

1. Create a blueprint derived from a C++ base class
2. HUD
3. add 1 static mesh
4. add 1 material

I am not able to find world outliner how to enable it?
