-        The work area rect (anchor_rect_work_area) is the usable space, excluding
-        exclusive zones already claimed by other surfaces, ensuring no overlap will happen.
-        This is the default behavior
+        By default, the layer_surface_v1 is anchored to the 'work_area'.
 
-        The full area (anchor_rect_full_area) is the whole space of the screen, ensuring
-        that the surface will touch all the screen edges corresponding to each anchor
-        edge that was asked, even if this would result in overlapping surfaces.
+        Anchor rect is double-buffered, see wl_surface.commit.
