I'd like some help with this. I've set up Multiplicity on my main PC and a Windows 11 ARM Microsoft Surface and it seems to be working okay for the most part. The audio has a noticeable lag so I'll have to abandon that feature. I also have no idea how to make the secondary computer (Surface) act as a second monitor for the primary computer (PC), so at the moment I'm able to switch between both as separate computers just fine.

My question more specifically regards mouse auto-hide. Let's say I start a YouTube video playing on my Surface which I have propped up with the kickstand. Then I move the mouse cursor back to my PC. Normally, if you're playing a YouTube video, Chromium browsers will know to hide the cursor after a few seconds of inactivity. Maybe Multiplicity is conflicting with this because the mouse cursor on my Surface never disappears if I switch to the primary PC once the video is playing and full-screen. The best I can do is try to get the cursor into the corner of the screen before I switch. The cursor is still there but it's less noticeable than if I switch across while the cursor is vertically centred. How can I make it so the cursor simply disappears like expected? (And any tips regarding the Surface's use as a secondary monitor for the primary PC would be nice too.)
