When updating the libtree, we modify the tree multiple times to avoid crashes on Linux. These generated events that buffered while the widget was frozen and resulted in redrawing the same footprint 4-10x. This reduces the buffering by discarding events that are generated during the freeze and only redrawing when there is a new footprint to draw
