I'm annoyed by these black squares which appears around meshed hair when i switch advanced lighting model on. I've tried it on other viewer such as Black dragon. It appears as well with deferred rendering on. Below is what it looks like when advanced light is turned off. Does anyone know what causes this and how to fix? I'm running SL on Windows 8 64bit with an ATI HD 4800 graphic card.

I added a "Feature this item on the landing page for category" for 7 days for my item [BOYAN] Realistic Red Carpet 8 Textures *full perm. The market place charged me 6 times within two days for this same request, stealing 1995L from me. Someone please help!!!
