We are using the relative pointer for motion events, but buttons and axis events still go through the absolute pointer device. That means additional DeviceChanged events that could be avoided if the buttons and axis events were coming from the same device as motion events. However, routing just the buttons and axis events is not sufficient. In Weston, clicking the window decoration of an Xwayland client gives us a wl_pointer.button event immediately followed by a wl_pointer.leave event. The leave event does not contain any button state information, so the button remains logically down in the DIX. Once the pointer button is released, a wl_pointer.enter event is sent with the current button state (zero). This needs to trigger a ButtonRelease event but for that we need to ensure that the device is the same as the one we send ButtonPress events through. Route those events along with enter/leave events to the relative pointer if available so that motion, buttons and axis events come from the same device (most of the time).
