scrolling should work, can you post a short example that demonstrates
the problem?

Here's one:
bigtext = urwid.BigText("hello", urwid.HalfBlock7x7Font())
bg = urwid.SolidFill('x')
overlay = urwid.Overlay(bigtext, bg, 'center', None, 'middle', None)
urwid.MainLoop(overlay).run()
BigText is tricky to deal with because it is a "fixed widget" that can
only be displayed with an exact number of columns and rows. Overlay can
handle fixed widgets (as above) by turning it into a box widget. Padding
can handle them by turning them into flow widgets.
Look for the light-yellow in these diagrams:
