[tripleabd]

after and before reinstalling the new patch/client of cata-beta i still see this problem with my terrain and textures
does anyone seems to have the same problem i have ?







i deleted my cache/interface/errors/wtf couple of times but still the same...
i searched in wow forums and in here in mmo forums but i dont really get what my problem is...
is it just me? and if there is a solution to this please post!
