Two screen shots of my problem. before i just wouldn't have a mini map in large buildings or cities but now it makes them unplayable with it glitching as it is. could be cause by any of the following, either cause of installing Burning Crusade, recent Ubuntu updates, or recent WoW updates. i'm using OpenGL and compiz is turned off. all the shaders should be set to where they have to be and a month ago when i last played this wasn't an issue. i have more than enough RAM, and my graphics card is an ATI 1050x. envy is not installed.

Hi,

Also try turning off the visual effects from system-->appearance. Also I had to roll back to the ATI 8.4 driver instead of 8.6/8.7 to solve my glitch problems. I still have no minimap inside buildings, but everything else runs fine.

I too am having issued with my mini-map, but it isn't solid white. My mini-map is transparent. I have the border, and the icons, such as my character location, but no terrain. Any ideas?
