Change platforms to ALL since it is occurring on Mac 07-14-11-M17 as well....

reassigning to hyatt.  I'm going to take a guess that this is a dup of the 
scrollbar bug where things start going blank after deleting.

[David Hyatt]

I can't understand what this bug is talking about.  Since I already have bugs on 
the tree widget screwing up when deleting, I'm just going to assume this is that 
same problem.

If you're talking about the problem with the brief blankness as you page down 
before content fills in, well, that won't be fixed by 6.0.  Sorry.

[Karen Huang]

Well. This problem used to exist. 
But by using 08-25-08-M18 commercial build, it seems that it's making progress 
now. I didn't see this problem for current build. Marking as verified.

[Peter Trudelle]

Wontfix is really the wrong resolution for this bug, since it means " The
problem described is a bug which will never be fixed." This was a problem, and
if it were still a problem, we would intend to fix it someday.

Comment 7

[Karen Huang]

Problem is still occurring on today's 09-07-09-M18 commercial build.
And based on Peter's comments, I need to reopen this bug.

Comment 8

[Peter Trudelle]

Thanks, but we still need a clear description of the problem, and steps that we
can use to reproduce it. Is this a temporary blanking *during* the scroll, or
does any part of the pane stay blank?  

Comment 9

[David Hyatt]

Yes, I do not understand what problem this bug is describing.  Please add more 
information.  Thanks.

Comment 10

[Karen Huang]

I mean temporary blanking *during* the scroll.

Comment 11

[Peter Trudelle]

Thanks!  ->future/nsbeta3-, clarified summary.

Comment 12

[selmer (gone)]

The blank spaces (still) don't always go away when you stop scrolling.

Comment 13

[Peter Trudelle]

Sounds like morphing here. Is there another bug for blank after scroll?  This
bug report describes a real defect, however minor, so I'd rather not morph it
into something else.

Comment 14

[selmer (gone)]

OK, the other bug is 54049.

Comment 15

[Peter Trudelle]

->moz0.9

[scottputterman]

There haven't been any comments in a while so I'll add what I'm seeing.  I
notice this mostly in the mailnews folder pane, though I have encounered this in
the 3pane.  Sometimes I scroll (generally up) and it goes blank.  Scrolling some
more will make everything refresh and be ok.  I've also noticed this in the
buddy list tree. 

Comment 18

[Peter Trudelle]

->bryner, but shouldn't be a problem with new tree widget.

Comment 19

[Karen Huang]

This is UI bug, reassign QA to Ninoschka. 
Ninoschka, please reassign to other QA if I was wrong.

-> mozilla 1.0 in anticipation of mailnews perf branch landing.

Comment 21

[[e-mail] (gone - use [e-mail] instead)]

On my primary machines (OS 9.1, Win2K, and Mandrake 7.2 with KDE) I'm not
experiencing this anymore.  There is a similar bug filed to Hyatt.  Bryner, feel
free to mark FIXED...

Comment 22

[Brian Ryner (not reading)]

Probably because of the switch to outliner.
