Bug. Dead player nickname is displayed over mobs, trees, ores

[fisher5]

Weird bug appeared inside Dark Swamp after player XerresDS died in DS. He let mob (Swamp Bog) kill him. After he died there was his nick displayed over monsters/trees/ores but only when I was holding shift and my camera was set between north and west direction.
