I would try showing the window before you take a snapshot
of it. Maybe even waiting a second or so to give the graphics
engine time to catch up:

info.Main_Window -> Show, 1
Wait, 0.75
info.Main_Window -> GetProperty, IMAGE_DATA=snapshot

Let me know if this works. :-)

Cheers,

David

P.S. I would have thought setting RETAIN=2 on your Widget_Draw
call would have solved the problem, though.
