I recently changed my address, and my state DMV says to put a sticker with the new address on the back of my driver's license. This hasn't been a problem for air travel before, but when I went through security yesterday the TSA agent told me I had to remove the sticker because it looks like I'm hiding something?

The sticker wasn't covering the barcode, or any text, and the reader works just fine with it on. Is this a new rule or this particular agent's preference?
