I've been using fluids boundryless mode at work while I'm cleaning. I suggest using full body tracking to keep the screens position relevant to me and to disable the head follow function so I can keep a window just out of my view until I turn to look at it. The screen constantly adjusting to keep the screen in front of my face is unesscesary and make it hard to see where I am going.

Also while I am mopping and backing up the window does not follow at all.

Lastly when using boundryless mode the screen will constantly try to reorient to a stationary mode unless I am walking very quickly, so I end up walking a short distance before the screen locks in place and I walk through it and it snaps back to being in front of me till it happrns again a couple seconds later.
