Actually, an incredible amount of 'bugs' are issues being caused by old addons, players not resetting their UIs or trying to and it not 'taking' for various reasons (usually Vista) or a need to update drivers.
Basic troubleshooting steps always start with a full reset UI. That puts everything back to a nice default level playing field so if any other issues are still present they aren't clouded by other software influencing the situation.
Q u o t e:
To do a full reset UI, you will want to save your addons in another spot if you wish to preserve them.
Then rename/delete or move your WTF, Cache and Interface folders while WoW is shutdown. Reboot your system.
Note, if you are running Vista make sure your permissions are set so it does not undo your changes.
More detailed instructions for different operating systems, including Macs are here.

Now, I'm not really qualified to give advice on drivers, but I know that's been an issue for some players - both graphic and sound. That could be better addressed in our tech support forum.
Known issues we've got a list above of the more pressing ones and these are and have been being addressed. There are also some workarounds posted for some of them until a more permanent resolution can be put into place.
