To reproduce this, load a page (I used http://uk.imdb.com) in seamonkey while your display is set to 16-bit color. When it's finished, switch the color depth to 8-bit using the control strip (or whatever). The page background goes black (from white). 24-Jan-99 build.
Setting all current Open/Normal to M4.
Changed platform to NGLayout to get the right Component selection
Looks like when switching between absolute and indexed color there's some confusion over the black and white palette entries (they're typically at opposite ends of the palette between Mac and Win32 and we're only seeing the problem on the Mac)
Reassigned to <dcone>.
per leger, assigning QA contacts to all open bugs without QA contacts according to list at http://bugzilla.mozilla.org/describecomponents.cgi?product=Browser

This needs to have the depthChanged event supported.
Look at the window implementation.. this should delete the offscreen buffer and create a new buffer and deviceContext at the correct depth. Then re-layout into this new buffer. If you need any help at the graphics level just let me know.. currently to get things working.. that event needs to be supported in the view.
