Black line through sms messages

Hi, I've recently downgraded from .451 to the official .425 because of some Bluetooth issues (which doesn't seemed to of fixed it anyway). I have noticed that some of my older text messages now have a black line through them, as if I've gotten a black crayon and drew straight through them. Most of the line disappears if I touch on them, usually all of it except for about the first 1cm of the line. I find this very odd, does anyone know what or why this I now happening and how I can fix it? Thank you :)

This is a known issue and there are other threads addressing it. Display your SMS messages as straight lines instead of bubbles and you won't see any more black lines.
