After playing a match of Traditional Through the Omenpaths Draft, the video display glitches across the entire menu bar at the top of the screen, showing with a faded white overlay with some icons oversized and other ones just displaying as white boxes. This carries through to every other tab as well. The only way to clear it out is to close and re-open the game. This has happened several times, but only with this event. I have attached a couple of screen shots to show what it looks like.

Also, the event description says that you are picking one card at a time, but it's actually a pick-2 draft.
