This feels great to me. This is the behavior of the touchpad of my HP ZBook with Debian 11 and Gnome. I just checked. I didn't check with an actual mouse because it's somewhere in some drawer but I can't remember where. Apparently that works on Macs only with the Magic Mouse, because: > However, with any traditional mouse, like the Logitech MX Master 3, the scrolling on the first window is cancelled and hijacked by the second window Does that mean that the mouse knows about the windows it is placing the pointer on? That seems weird. That kind of intelligence should be in the window manager (whatever it is on a Mac) and not inside an external device or more probably its device driver. If that was the case, all pointer devices should behave in the same way.
