It’s a cosmetic and in some cases a functionality issue that I like to address - after a month of unsuccessful tinkering to get an acceptable result concerning the following:
A compiled game loses focus of game viewport (a secondary user triggered mouse click is necessary to grab focus of the game viewport in all instances throughout a game).
A huge improvement could include an automated script or blueprint to “fix” this.

I am looking forward for an update and hopefully a solid solution.
This is a known issue that is currently being investigated (UE-13053). We understand the urgency of this bug and want to ensure proper functionality without impacting other sections of the code.
