well it looks like the graphics artifacts that was plaguing me a few short weeks ago.
- did you update your config.plist that sets CsrActiveConfig to 0x43
- slide=0 boot arg
- and use the standard graphics kexts - vs any rollback etc.
- how much memory do you have - 8 GB seems ideal.
also, you could try using OsxAptioFixDrv-64.efi (needs 0x43 setting) instead of the "Fix2Drv"
