It's sort of dismaying that screen mirroring is getting features like this out of the gate, but iPads running iOS apps are still stuck with iPhone SE screen rendering, when they could easily support Max screens. :\
Yeah same here, has become completely unusable, shame now that the mouse is working. Get the same on M2 and Intel based machines.
Also does anyone else use this on separate machines and find your other machine flooded with notifications when you turn it back on, it needs to dismiss the notifications from all devices when viewed/dismissed from any other.
