Hopefully this is the proper log.
But all the spectated games I've done (maybe 3 or 4), the bottom 3 players on the purple team do not have portraits. This is both the side bar and in the scoreboard. Their individual stats in the bottom left still show, just no champion image for the rest of the interface.
EDIT: Also, when running on borderless windowed mode, the mouse does not lock into the window. In the case of running dual monitors, when you try and pan with the side of the screen, you simply just pop onto your second screen. Not a huge concern with the directed camera and the much easier and smoother drag scroll (WHY ISN'T IT THIS NICE IN REGULAR GAMES?).
