210250 - [native scrollbar] Content area doesn't fill dismissed space (white) at bottom of page)

Status: RESOLVED DUPLICATE of bug 222300

(Core :: XUL, defect)

Description

[Chris Casciano]

If the Summary sounds familiar, it is. Lately I've been seeing the same behavior
as bug 155013 (filed on moz)... but with a white "dead" area. Basically, any
time you are scrolled to the bottom of the page and the content height changes
(either by script or by making your browser wider so the content reflows) you
get dead space at the bottom of the window. The document *should* stick to 

This doesn't happen in mozilla builds (recent trunk nightlies).

This does happen in recent Camino builds including 2003061704... but I won't
know without testing a few builds if its a recent regression or if I'm just
noticing it recently. That info coming as soon as this is filed and on the record.

Steps to reproduce via included url:

1) Load Page
2) Scroll to bottom of the page
3) Click "TV / Net Appliances" - page grows in height and scrolling sticks to
the bottom
4) Click "TV / Net Appliances" again - section collapses again - content area
shrinks off the bottom of the window... scrollbar gets all out of wack

The make page wider method works on any page that you need to scroll down on

marking this as a regression... of sorts...

0.6 & 0.7 had this bug..

2003032008 was good
2003032705 was good
2003040905 was bad (dark grey)

... and the few random nightlies i tested since 4/9 had the bug but varied
between displaying the dark grey, the pure white i see now, or my default bg
color of a slightly off white. Unfortunatly I don't have any nighlies saved
before 3/20 to test when the first shit from bad -> good happened.

This bug seems to have some similarities with Bug 203467.

In both bugs the page content doesn't stick to the bottom side of the container
window causing paint problems of background colors and paterns.

Please test in Mozilla builds with the Classic skin. I bet that you see it
there. Probably a native scrollbar issue.

Comment 4

[Chris Casciano]

hmm.. mozilla / classic seems to have another variation of this problem in that
the content area pulls away from the bottom but it doesn't repaint the bottom
area at all leaving lots of artifacting

[Chris Casciano]

so yeah... mozilla 2003062308/trunk os x w/ clean profile using classic skin is
pretty broken in this regard too... but  since the appearance is very different
between the two (camino & mozilla) I'm going to leave the decision to move this
bug to Browser->XP Toolkit/XUL Widgets up to someone who knows the code enough
to say that one patch can fix both

Comment 6

[Chris Casciano]

so um yeah.. forgot about this one...

looks like this is a total regression away from the work done in bug 155013...
reassigning to browser
