Zalmarath Bug

When I was leveling my second character I noticed on Zalmarath on act 2 when you get too close to the edge the screen jumps for a quick second like the program is confused where the player is or something here is a link https://drive.google.com/file/d/1AwYd6-td0ZMlvSMHjL3BDDzPeiZ-Xb6n/view?usp=drive_link

I continue to have this problem as well. It's so disorienting I can not kill him.

I've had this bug too, it makes melee builds against him nauseating and unplayable. I consistently fall through the ground or get bounced up into the air. I cleared the boss when I flew up instead of down and got stuck on the geometry or something, where it couldn't hit me but I could still hit it.

After the fight I wasn't able to get out because I couldn't move or reach the portal I spawned by pressing the portal button, so I had to close the game and log back on to reset the instance I was in to free my character.

Also this might not be a bug and is nowhere as bad as the other 2 bugs, but only the arms have hitboxes and the chest/head region doesn't damage it at all.
