46648 - Subject Pane paint problem when scrolling

Status: VERIFIED FIXED

(SeaMonkey :: MailNews: Message Display, defect, P3)

Description

[kinmoz]

Using my mozilla Win32 6am Debug build ...

I use IMAP, with a pref setting of "Mark it as deleted" when deleting messages.

If I scroll down to the very bottom of my subject list in the subject pane, and
delete all the visible messages except one of them, and then select
File->CompactThisFolder from the menus, I end up with a subject pane with only
one subject visible at the very top of the pane.

If I then click on the subject pane's up arrow in it's vertical scrollbar, I see
the first line of the subject pane being painted over with new subjects without
the previous contents being erased, and the last subject in the list painted
several times .. by several times, I mean that it looks like it is putting
duplicates of the last subject in the list each time I press the up arrow.

Before I reassign to hyatt, I wanted to know if it really is putting dups in or 
not?  If it's not then it sounds like a tree painting problem, if it is (i.e. 
you can select them and do things to them) then it could be a mailnews problem. 
Is this only happening with Compact Folder?  Sounds related to some of the other 
scrolling bugs hyatt recently fixed.

It's not adding dups to the subject tree, it just looks that way, because of the 
paint problem.

By the way, I should also mention that I've seen this happen even though i 
haven't delete/compacted anything.
