the process is painstaking to go back to lol; but I'll describe it.

If I drag the window to move it; it will show the desktop upside down in the box and if i move it; it just repeats; It's like a screen tear but it mirrors the desktop. It's very strange and it's hard to describe but basically is what i said... It's like really hard to explain.. =.=;

If I scroll a window the content of the window will turn upside down..
say I was looking at a website on safari; it will just turn google upside down. I'll get some images up tomorrow if you still don't understand.

How did you install your graphics card? or did it work out of box?

NVinject 1.2.1 works like a EFI string; QE/CI disabled.
I know NVkush enables it, not sure about NvDarwin.
