[sane-devel] Xsane "preview" glitch, FYI

FYI, I've noticed a problem with the Xsane preview window. I'm
currently running xsane 0.999 on Ubuntu 22.04 with Gnome or Cinnamon,
using an Epson USB scanner with epkowa driver, but this xsane behavior
has been similar for previous versions.
When I open xsane, and then use VIEW and check the box to enable the
preview window, that window comes up, but the display acts as a 1-pixel
window in both the vertical and horizontal directions. I.e., all of the
preview scan, even the mouse cursor and UI such as "Acquire Preview",
appears in a single pixel line on the left and top sides of the window.
The workaround for this behavior is to QUIT xsane while the Preview
window is visible (the View checkbox is checked). Presumably that
configuration is saved when you quite xsane. When I then start xsane
the next time, the preview window comes up at startup with all the rest
of the GUI and works as you'd expect.
Certainly not a critical bug and the workaround avoids the problem. May
be a bug somewhere in Ubuntu rather than xsane. But I thought someone
might want to investigate, or perhaps add the workaround to the
'Problems' menu.
