I experience this bug even if both monitors are set to 1024x768. I can only run dual monitors w/ Compiz turned on if I set the LCD to 1024x768 and the external monitor to 800x600 or lower.
Checking if it's possible to run Compiz on your system...
Checking for texture_from_pixmap... [ OK ]
Checking for non power of two support... [ OK ]
