My theory is, the people that have it hate it, and the people that don't just don't realize how atrocious it is.
Apparently not. Apple's official response is:So 10.5.1 is here and I take it there's still no solution?
Others state that the translucent menu bar is rendered slightly differently (with a slight curve) than the contextual menu (right click) and therefore doesn't work on the 5200. Yeah, that sucks folks.Some graphics cards, such as an NVIDIA GeForce FX 5200, may not have the necessary OpenGL capabilities to display a translucent menu bar even though they are compatible with Core Image. Those cards should render most effects, but not the translucent menu bar.
Hopefully, it was a deliberate design decision - not just something that slipped through.
