35131 - Loading images should have transparent background

Status: VERIFIED DUPLICATE of bug 1248

(Core :: Layout, defect, P3)

Description

[hand]

When the browser is loading images, sometimes the unloaded parts of the images 
are either black or contain mostly black garbage.  This usually occurs when the 
page is hidden behind another window while loading, then brought to front again 
before all the images on the page have been loaded.

This effect is worst when the browser fails to completely load an image causing 
the unsightly unloaded parts to stay permanently.  (I would not classify not 
being able to load an image properly as a bug - after-all, networks aren't 
always reliable, but see bug #35130.)

So again, a transparent background for unloaded portions of images would be 
ideal.  A coloured background matching the background colour of the page or the 
background colour of the element in which the image is contained is less than 
ideal but preferable to garbage or black.

Don, I thought this problem was fixed? Is the fix in PR1?

Testing with 2000-04-06-10-M15 and 2000-04-07-09-M15 on WinNT viewing a variety
of graphics-rich sites while doing a download at the same time to keep loading
slow, I saw no problem with unloaded parts of images containing black
or garbage.

Rubber-stamping as verified duplicate, pending [e-mail] providing 
information to the contrary on a current build.

Thanks, Sean!
