--- Comment #12 from Horia fakemoth@gmail.com --- Tried it right now. This doesn't do anything - the behaviour is still the same. The game just doesn't work anymore with OpenGL.
And this doesn't seem to me as a " Importance: P2 minor" bug. I just quitted playing WoW because of this. Directly or through the launcher with -opengl or without doesn't make any difference. Nor the Wine version.
On openSUSE 13.1 and 13.2, nVidia or AMD proprietary drivers no one plays this anymore. Not on a big resolution and decent conditions anyway.
