[sane-devel] Problem with color shuffling using an Epson Perfection 610 ,

[Martin Krüger]

Hallo
I found another Bug introduced between sane 1.0.19 and 1.0.21.
Using xsane to aquire an preview-scan over the full plane in color mode
fails. If you aquire an preview in bw/grayscale-Mode or over a part of
the plain works well.

I did a bisection wich led to this commit:

epson2: fixed color shuffling bug for Perfection 610, added more debugging


Without further investigation i suggest:
To increase the plane to scan for some lines to compensate the
color-shuffling fails when you already selected to scan over the whole
plane.
