open http://bugzilla.mozilla.org/showattachment.cgi?attach_id=32282
it's a png image larger than my screen - 1462 x 922

when i scroll the page after its loaded, the image shows corrupted.

oddly, if i scroll the page while it's loading, there is no corruption.


Reproducible: Always

also seeing this with this image: 
http://subversion.tigris.org/subversion-diagram.png
on page:
http://subversion.tigris.org/project_status.html

corruption also shows if you right-click on the image and then dismiss the
context menu -> the area under the menu will be corrupted.

Comment 3

[Aaron McBride]

It looks like the region image is being repainted from 0,0 of the images instead
of x,y - the start of the region.
