My hackintosh is suffering from a artifacts/ a horizontal line (shifted display) at the bottom of the page of the secondary display when starting to display Adobe Flash in the browser eg. at Youtube or displaying Quicktime-App in OS X Lion 10.7.4. Only system definition MacPro 3,1 doesn't have this problem. I want to have multiple P-states that's why I'm not using MP3,1.

<key>AtiConfig</key><string>Vervet</string> in org.chameleon.Boot.plist. 5770 and vidcard is recognized as a 5770 in System Report. Tried also stability of 5770 in Lion --> 5 hours of Unigine-Heaven-3.0 Demo no problemo.

• I've tried System definition iMac 12,2, Macmini 5,3, Macmini 5,1 and removed AppleGraphicsPowerManagement.kext from S/L/E still suffering from the odd line. sound is terrible.
  
• SD iMac 12,2 altered S/L/E IOPPlatformPluginFamily.kext --> ACPI_SMC_PlatformPlugin.kext to Macbook Pro 8,3 for P-states still suffering line

I thought "well OK try my Asus nVidia 9400GT passive!" Installed it with SD iMac12,2 and bammm.... no glithces, artifacts or line when playing Youtube movie or using Quicktime-App. Only performance is not okay. Scrolling in Browser is choppy, Hardware Acceleration in Photoshop CS5.5 is choppy.
Digging through topics here, at Tony's Forum or even Google doesn't help me much ;-(

What do I overlook guys?
