[xubuntu-users] SimpleScan paper size issue in Xubuntu 20.04.2

[MR ZenWiz]

Since Xubuntu 20.04 came out, the built in SimpleScan utility, now
called Document Scanner, has been giving me headaches with its new
layout.

The one that really eludes me is the paper size preference.

I found, to my delight, that I can set the Preference for paper size
to Letter (8 1/2" x 11") and get letter-sized scans from the sheet
feeder, instead of the "automatic," which is always legal sized even
when the paper is not.

I figured this would be a great default setting since I almost always
use Letter-sized paper, until I scanned a single page - scanned the
letter sized paper just fine, but the scanned image has 3" of black at
the bottom to fill out the difference between letter and legal sized.

WTF???

If it's set for Letter sized paper, why isn't that good enough for
both the platen scan and the feeder scan?  If not, what does
"Preference" mean?

It's really annoying, and I'm wondering if anyone knows why, or to
whom to raise this issue if not here?

Thanks.
