Sorry for posting a me too, but since Debian switched GNOME to Wayland in 3.26, I see this behaviour as well. Sometimes the mouse cursor freezes completely for multiple seconds, e.g. when compiling stuff or transferring large amounts of data over USB. This is with the intel driver (X220). I don't see this behaviour with the GNOME on Xorg session. I'm happy to run further diagnostics if needed.
