valgrind finds one 352 byte leak with celestia. That can't possibly explain the issues you're having with WoW.
I raised this as a separate issue for a reason... ;-). But I doubt that Mesa contains functionality that is *specific* to WoW; other apps *must* be affected by #74549 - although perhaps not as noticeably.
