  1. I'm having the same issue. 3d games run perfectly. Most anything 2D (especially darker areas and flash videos) produce small blue/green pixel-sized dots randomly on the screen. It's ridiculously annoying and I'm about to return the cards and wait for Fermi.

    I've now wasted about 4 hours of my life troubleshooting with no progress. I'm not OC'ed at all, but that shouldn't matter since the 2D clocks are fixed. It's definitely not a heat issue since the cards are running 41c idle/58c load after several runs of Vantage. The cards are Powercolor liquid cooled versions so it's a SOB to move any of the hardware:

    Switching between single card and Crossfire
    Changing resolutions (2560x1600, 1900x1200, 1650x1080)
    Ensured my DVI cable (which works flawlessly on other cards) is secure between card-monitor
    Switching PCI-E power cords between the cards
    Switcing the DVI cord to another DVI port on the cards.
    Changing the two "DVI reduction/enhancement" options in Catalyst
    Changing the Crossfire connector and its placement
    Re-seated the cards
    Reinstalling Catalyst 9.11

    Apparently, many people are seeing this with 58xx cards... Here are just a fraction of the threads with this complaint:
