    Followup: I managed to create a reproducible situation.  Here's how:

    I have a message that appears in both "Unread Inbox" and "Flagged" 
(because, at the moment, it's both).  I noticed that I had been in 
"Flagged" just before seeing the message scrolled down about a line 
in "Unread Inbox".  So I went back to "Flagged" and viewed the 
message there, and it was scrolled down a bit more.  Back to "Unread 
Inbox", and the message was scrolled down yet more.  Not exactly a 
line each time, but close.
    As I went back and forth between mailboxes and viewed the message, 
each initial viewing would scroll the message down a bit more-- but 
JUST on the initial view upon entering a mailbox.  Any further 
viewings before leaving the mailbox would leave the new scroll state 
unchanged.
    I'm also able to induce this in other messages in "Unread Inbox" 
that are not flagged by going to my actual Inbox (that shows all read 
and unread message) and then going back to "Unread Inbox" and viewing 
longer messages.  It doesn't happen to all of them, but some of them.
    I can shoot a screencast if the description above is unclear or confusing.
