I just finished a quick play match, during the match my weapons became transparent and so did the players on both teams. I captured a portion of the video on my console just in case you would like to observe the video.
I've had this problem repeatedly since the patch on Tuesday. I'll save and upload a video soon. Matches start out normal then it gets progressively worse as the match goes on, with both enemies and teammates becoming invisible, and eventually my own character / weapon / reticle. It's very frustrating.
