I just loaded it up, and from bed, you can still hold F and mouse out cause its not a “hard boundary”? Its like it bounces out of window and back if I try to mouse out of frame, which should be fine in most scenarios but its not “hard locked” to the application. Like its bouncing between my 2 monitors, and not “totally blocked” by the edge of the window.

I would record it and show you but I dont know how I would do that across 2 monitors if Im being honest. If i mouse left to try to get to second monitor, it looks like the cursor is jiggling at the edge of my screens.

Hopefully that makes sense. It rubber bands back into the window, rather than stopping you, so you can still jump “out of active window” on a mouse click.

hmm it does work perfectly fine for me. Do both monitors have the same resolution? Can you try going into fullscreen with ALT+ENTER and see if that fixes it?
