Armor Bar and Other HUD GUI are placed incorrectly in survival/creative.
When playing in survival, the armor slots underneath the health bar has a gap between both of them.

This also affects the other GUI elements on screen such as Horse health and absorption affect hearts.
(Worth mentioning that it's also affected in creative as well. When riding a rideable mob, their health is displayed lower than where it's supposed to be).
