This site uses transparent background images in some divs.  However Mozilla
often displays the transparent sections as black.

The site validates as XHTML 1.0 Strict and CSS2.

Reproducible: Always
Steps to Reproduce:
If the problem doesn't occur immediatley try minimizing and restoring or
scrolling the images off the screen, or hiding the window behind another and the
showing it again.


Actual Results:  Transparent sections appeared black

Expected Results:  Transparent sections should be transparent

I've only had this problem when running Windows 98 on a sun-pci card.
I haven't however been able to test it on any other system.

Is this a duplicate of the "Animated transparent gifs have black backgrounds" 
bug?

Comment 2

The images involved here are not transparent, they are used as the backgrounds
to block elements.

Dup of bug 78733? Deals with transparent gifs in table backgrounds.

Comment 4

Bug 78733 sounds the same but is about background images in tables, I guess
however that the cuase is probably the same.

Making a dup of bug 83726 (specially created for all the "transparent GIF turns
black upon redraw" bugs)
