I just checked blockchain and the transactions are there.
So I restarted bitcoin-qt and now it's showing everything as confirmed again.

I'm guessing it's just a visual bug?

I have a bunch of old BTC transactions between 4/10 and 4/12 that were confirmed long ago.  But somehow today, they all suddenly appeared as not confirmed.  Newer transactions are not affected.

Any ideas what's going on?

A confirmed transaction can drop to unconfirmed if was double spent when a block reorg had a different transaction.   That doesn't happen a whole lot, and the transactions affected during the March 11th hard fork were the only ones since 2010 that a transaction with six confirmations on the longest chain reverted to being unconfirmed.

So if you had a confirmed transaction revert, it would have had just one confirmation most likely,

Check to see if the payments show on Blockchain.info.

More info: this is happening in 1 single wallet (though I only have one), across multiple addresses, on Bitcoin-QT v0.8.1-beta
