Might get mine done under warranty when in for first service. It's not that bad on mine but still there every now and again. That said it's the same on my friends older monster (dial clocks).
My 1098s has always done this and I was told to take a phot of it when misted badly and they will replace it but as early mentioned it would be pointless unless they have modified the replacement parts. The LCD failure point may be more of an issue though! Not much warranty left so will need to force the issue.
