Have you tried changing the environment?
When I first started up after the patch, I had an entirely black screen. Sound worked, no visual.
Something that was mentioned on the blizz fora was to go into winecfg and set the environment for battle.net app to be XP.
Even tho I launch wow from CLI, that made it so it showed up visually.
No clue if that will help you, but might be worth trying.
