I installed WoW a few days ago, but I wasn't able to start it up because I apparently didn't have DirectX 9.0 installed. No big there; tracked it down, installed it, and all went well. I managed to start up the main client with no problems to speak of, logged in without a hitch, and restarted the client to patch, which is where I started having problems.
Once the client finished patching, I restarted like it asked, but now I have some really strange glitch that's been going on every 1/10th of a second or so, where the screen almost seems to split in half and gets some sort of kalaiedascope effect before going back to the normal screen. Best as I can tell, it has something to do with the fire animation in the background, but other than that I have no idea what's going on. Anybody have any advice to offer to a n00b?
