Area #63 is a living heck.
How that heck looked like - https://imgur.com/Jd1ABVK
The clip above is short, the screen shake lasts long enough to make you decide to go ahead and close the game.
I believe the shaking is caused by warriors' power smash, the shake is much worse for other players than the warriors themselves.
My guildmembers actually have recreated the same shaking from the clip above.

If you have intended the smash to cause that sort of shaking, THEN PLEASE, PLEASE ATLEAST REMOVE IT WHEN CHOOSING LOW SETTINGS.
