Only draw the depth buffer when overlays are enabled and scene or view has changed. When using Cycles in the viewport for every viewport draw call the depth buffer was renewed. Draw calls happened when a sample was finished or the status report was updated. This could waist some CPU/GPU cycles. This change will check when the depth buffer needs to be updated or when the last known depth buffer could be reused.
