    Question distorted display

    I often get a distorted display when using Safari, where all text becomes unreadable. Just now, while loading a page in Safari, the display became unresponsive and wouldn't let me click anything for almost a minute ... when it came back the text all over the screen was distorted (as if it were smudged or behind water). I see many entries like the following in system.log:
    Code:
    Nov 17 19:29:02 myhost kernel[0]: NVDA(OpenGL): Channel exception!  status = 0xffff info32 = 0x3 = Fifo: Unknown Method Error
    Nov 17 19:29:02 myhost kernel[0]: 0000000b
    Nov 17 19:29:06 myhost kernel[0]: NVDA(OpenGL): Channel exception!  status = 0xffff info32 = 0xd = GR: SW Notify Error
    There are also many entries like the following in windowserver.log, but none that seem to correspond with the timing of the NVDA errors above:
    Code:
    Nov 17 19:50:53  [112] kCGErrorFailure: destroyBackingSurface : IOAccelWriteLockSurface = e00002bd

    I don't know whether this is a kernel problem (9.8.0, based on Voodoo) or graphics problem (NVKush, GeForce 7600 GT), or if they're two separate problems ... or how to go about checking or fixing this.

    I tried using NVinject instead of NVKush ... seems liek it may be a bit more stable, but under NVKush, my card listed "Supported" for Quartz Extreme, QuartzGL, and Rotation in Profiler, but under NVinject, Quartz Extreme is not supported, and Rotation is not even listed.

    And now I've tried NVEnabler, but that ended up with a black clear screen, with a mouse pointer that I could move but do nothing with.

    I don't know what else to try. From LSPCI, graphic info is:
    02:00.0 VGA compatible controller [0300]: nVidia Corporation G70 [GeForce 7600 GT] [10de:0391] (rev a1)

    Using OSX86Tools, I get this plist:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">

    		<string>nVidia GeForce 7600 GT OpenGL Engine [EFI]</string>
    	</dict>
    </dict>
    </plist>
    Any hints on what to do with this, and which injector will work?

    And now I've tried the only other method I know of: adding my EFI string (obtained from OSX86Tools) to the boot.plist. This resulted in the same as above: black-gray-ish screen (but not a dead monitor signal) with a movable mouse cursor and nothing else.

    So I cleared out all NV* kexts, restarted, got plain VGA mode with low res and no QE support. I then added my monitor's native resolution (1920x1080) to a boot string, and the res is higher, but it appears stretched out and crappy, still no QE support.

    How the heck can I get decent resolution and Quartz Extreme support, without my screen getting distorted?
