I've been using nested rootston inside KWin and noticed problems with content refresh when using touchscreen. It worked better with mouse. After debugging, it turned out that: - rootston doesn't register to wl_touch, so KWin emulates wl_pointer events - when emulating, KWin sends naked wl_pointer.motion and wl_pointer.button events without sending any wl_pointer.frame with them wl_pointer.frames are sent when using mouse or using touchscreen with a client that listens to wl_touch; they just weren't when emulating wl_pointer out of touch for clients that don't.
