In The Armory, I encountered this floating item text after swapping several characters in the party. The "Apprentice Boots" details continue to float over the rest of the screen, which otherwise responds as normal to dragging and item selection. Perhaps in the add/remove process, an item was displayed and then the character removed before the item context disappeared?
Try doing it very fast and many times ! http://www.cardhunter.com/forum/threads/graphic-bug-during-skin-change.895/
