Very often there is a bug that leaves the camera shaking when you fly away from the bracha in creative mode. Clearing the effects with the command does not work. The shake effect hangs on the player indefinitely from 00:00 time to the end. The only way to fix this is to approach the brachi again and slowly walk away from it.

Sometimes it is fixed by the longer duration of the effect

I have seen this, don't know a fix for it at the moment, it can also be fixed by relogging

I think this should be fixed in the next update! If not please open another issue
