How to disable?

What is this feature called and how do I disable it? I've had my device for a year and a half and it still trips me up to this day. Dimming my device before screen off is fine, but the lock icon makes drives me mad.

This feature is part of Samsung Game Booster and is designed to prevent accidental touches during gameplay. 

To disable it:

Open the Game Booster settings from the floating icon while in a game.

Tap the Settings gear icon within the Game Booster panel.

Look for a setting related to "Block during game" or "Auto screen lock" and turn it off.
