Avoid horizontal pixel-height lines of the background appearing when "fast scrolling"

Browse Source 
down the page.  There is a similar problem with scrolling up pages which may be a bug
in ami_do_redraw_limits or plotters (probably bitmap tile plotter), as drawing
additional pixel lines after scrolling is not redrawing the affected area.
Example sites where this problem is apparent:
http://www.nintendolife.com (border pattern does not redraw)
http://www.amigaos.net/content/72/supported-hardware (clouds show through the main
text area)
