What is the best/shortest way to reproduce the problem?
Download the pokerstars client from http://www.pokerstars.com/ and install. You don't need to log in (which means you don't to create an account), just observe a table and you'll see the underlines in the chat.
You may also want to install arial and tohoma fonts, I haven't checked to see if the bug shows up without them. I don't think you'll need any other workarounds or tweaks to see the bug, but in case you do they're shown at http://appdb.winehq.org/objectManager.php?sClass=version&iId=2899
