I am on Arch Linux but affected by the very same issue. There is another
workaround that worked for me:
running with --sync (i. e. xsane --sync)
Looks like the preview window gets created on each startup and then later -
corresponding to settings -
either it's left as is or hidden. Maybe if it's happening too fast (w/o
sync) this leads to corruption.
Quick and dirty semi-solution (certainly not ideal but al least working
100%) is to discard the hiding part (that is:
ignore the setting at startup):

I do hope someone knowledgeable steps in and prepare a proper fix.
