"Fallback option for unsupported computers
Apple has provided a fallback option for computers without graphics cards
supported by Core Image. You'll still be able to use Core Image but your CPU
will do the work instead of the graphics card. This will obviously be slower
than the GPU in most cases, however it's still functional with a few
exceptions. One of these is that you won't see all the effects and eye candy
you would if you had a supported graphics card (such as the Ripple effect
when opening a Dashboard widget). The Ripple effect requires a programmable
graphics card due to the nature of the effect, and although it could
theoretically be rendered by the CPU, it would be so horribly slow that it
wouldn't be worth it. Because of this Apple makes certain effects
unavailable to the CPU fallback option."
It seems 'software' CI is the fallback so it may be your problem. My
particular problem occurred with CI off when viewing zmags with their viewer
at the Netto supermarket site - white banding was apparent across the pages
- so perhaps Safari calls on CI to render certain features.
