In Panther, the display is fine.

After rebooting from panther into linux, I get the same problem. It is
fairly minor really, and is related to areas of bright color on the
display.

For an example of what I see, check here:

The rain is highlighted with green markers.

This is with a sony CPD-E500 display. It is similar to what I was
getting with the apple blueberry 21", although on that, the rain was
more pronounced, and was not vertically aligned, but diagonally aligned.
