Those requests are received while dealing with the ::layout frame clock phase, this has the unintended side effect of making the frame clock "rewind" to handle ::flush-events again during this frame, which delays everything and practically halves the frame rate. We do intend to make the motion events dispatches on the next frame, so do this in an idle at a slightly lower priority than layout/draw, so the ::flush-events phase is actually requested for the next frame. Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3264
