Graphic effects glitch/corruption ATI/Radeon

I'm using an ATI/AMD Radeon HD 5800 series, with driver 7/28/11 (version 8.881.0.0, aka. Catalyst Control Center v11.9).

Running Windows 7 64bit with 24gb of RAM, SP1, latest Windows updates, Xeon processor.

On this computer, I'm seeing a lot of NEW graphical effects glitches in beta5 (that were NOT in beta4).

For example, when I'm being attacked by mobs that use ranged explosion-based attacks, and when I attack them with something that does an explosion effect such as this Demon Hunter using a magic arrow, etc.

Here are screenshots:

I have a lot of computers. I'll test this more on my other computers this weekend, and I'll post more replies with what differences I find.
