In a vehicle, idle, while being in a raid with bags open.
This time in a raid. The only thing isn't showing is DXE bar timers they appear above the left chat pane then move to the poweraura bar in the finals seconds. Recount is hidden and appears above the minimap and part of the right chat pane.
edit: forgot to mention there are 2 3x4 buttons hidden in the UI, one box is placed between the action bars and the minimap and another between Omen and the actionbar. Those are mainly set for random things like pets, quest items, professions, etc.
