Damage Visual Feedback delayed

When taking damage, sometimes the visually feedback (the red blood image) doesn't appear until almost 30% of your health is gone.

Please excuse the overexposed video, nvidia's app and windows HDR don't get along sometimes but in the vid below the red incoming damage indicator doesn't show until my health is decreased by about 30%. It should be alot earlier, i.e. as soon as my ES or healthpool drop below 100%
