while walking around in survival mode, the right side of the screen seems to intermittently go blank.  This blank spot seems to correspond to where the player would be holding an object in the right hand, but the texture and its surrounding bounding box is replaced with a blank image.  This happens randomly every few minutes and lasts a few seconds.  the blank box always reaches the top and bottom of the screen.  the left extend seems larger or smaller if the player is turning.

I've been playing for about 6 months and this just started happening yesterday.  This was happening on the right player with split screen mode.  (I always play split screen mode)
