There has been some reports of a game issue where players have experienced a glitch where their loading screen looks over exposed, turns black and then the town screen looks distorted and over imposed.
Loading Screen flickers and over-imposes

This issue seems to be caused by having lower resolution and Origin in game turned on.
Suggested Solution is to turn off Origin in GameDeactivate Origin in Game -- Open Origin, Select Origin > Application Settings > Origin In Game and deselect to disable Origin In Game.
