This is a Coinbase Bitcoin address: 1AKLdrqC4mngw5m55HTtZEY3mtTuxySgb, and this QR code: https://i.imgur.com/GE0c2Mf.png is the one Coinbase provides.
You can see that the QR code shown on the blockchain.info page is different from the one on Coinbase. Is there something I don't know, or could this be a bug?

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

QR-codes can be generated in different ways, for example with different level of error correction.
That means that 2 QR-codes having the same content do not necessarily look the same. This is normal.

You can check that both contain the same address by eg. scanning them with your phone and comparing the address that they produce.

No, it's a correct code, I have checked it, even though you see it slightly different.
You can check the QR code before sending bitcoin to the address obviously, so no need to worry about it.
