when playing singleplayer in the beta release the screen can glitch out

just simple walking around or standing still or eating in the beta makes screen go black and some times glich out making vibrent colours pop out and flicker at a very fast rate 

 

 

black screens can last 3 seconds or more with the game running   very annoying and unplayable.

 

 

 

may be unrelated but wold got deleated so yeah
