Not too sure how I found this, but if you Grey Talon Ult into the window (right at the bottom) behind the matchmaking dude, it goes through the map geometry, I tried to attach a video to this post, but not sure if it is properly attached.
The Icon for mirages gun, found by hovering over the gun items in the item shop in the bottom right, shows McGinnis's turret instead of Mirage's gun as it should. This is just a cosmetic issue, but something I noticed. (image attached)
