[2020] Apex legends bug and story mode singleplayer

Hi @wraith5556, 

Thanks for taking the time to write this up! We appreciate the feedback. 

In regards to the UI issues you've been seeing, it is usually related to the command line arguments like you mentioned. Off the top of my head, I'm afraid I don't know specifically which of these arguments would be causing the issue. In other cases where I've seen this issue, removing the command line arguments will stop the UI flickering issues.
