At first I thought it was my connection, but it seems to not be from what I can tell. Randomly, sometimes when switching weapons, weapons and eventually players will enter the transition animation where they're invisible with a shimmer effect but it'll never go away. It's made the Crucible unplayable. I've linked a video above. Most of the time, it lasts for the entire match. Sometimes it'll get a bit better and load my body or another player's body back in, but not always. Some players are more affected than others, too, with just their weapons invisible or even no issues at all. It's super weird.
