I downloaded and compiled it tonight. It shows problems similar to
scanimage, not xsacnimage.

Other than the size and position of the scan window, the options were
the same: 8 bit color, various resolutions over the same region. Here's
another problematic scan. The first one is good at 300 dpi, the second
is garbled at 720. (I had success right up through 600 dpi).

2.2.19 I know, I should upgrade to a 2.4 kernel.
