Comment 3 for bug 831512

1.) yes, this exists on 12.04
2.) yes, using LIBOVERLAY_SCROLLBAR=0 xsane makes xsane render with the old style scrollbars.

I suspect that this is desired behavior, but because the scrollbar widget itself is the primary purpose where it is used here, the overlay scrollbars are confusing at best. Ie, they're really more of a "slider selection utility" here. Thats different than the case where a scrollbar is used for scrolling content inside a pane.
