Heya, can anyone with the MP and ATI 4870 confirm graphic issues with the user interface, especially with the action bar ? Everytime when the UI should light up (e.g. after a cooldown or usage of an action) the lighting effect is distorted, flickering, messed up or completely missing. When I pop the GT120 back in, everythings fine. When I play with the 4870 WoW on Windows, everythings fine. Just WoW running on 10.5.6 with 4870 seems to have troubles. I already cleared the cache, interface, WTB and WTF folders, even reinstalled and patched from scratch, still happens. Anyone else ?
