WotLK Menu sliding (i don't know how to name it)

[DKB]

I downloaded the Warmane wotlk torrent from the webpage and it's all good, there's only this exception:

Blue lines are joining things that should be lined up, but buttons and text highlights start sliding after 12 or so quests, and i happens with regular text as well (like asking a guard for directions)

Am i the only one that is having this problem? is there a way to fix it?

Anyone? Am i the only one with this issue?
