Using 2000090708, this page loads a banner ad at the top. After about 5 - 10 
seconds, the banner mysteriously shifts to the left about 5px. Is something 
triggering a reflow well after the page is already loaded? This is a cosmetic 
bug, but random shifting of page contents may be disconcerting to users. This 
occurs on other pages as well and URL's will be added to this bug report as they 
are encountered.

It appears to be related to animated GIF's. It is always occuring where there 
are animated GIF's anyway. On this page, just load it and watch the area around 
the animated GIF shift around at random. Reload to watch it again. Playing with 
clicking in the page and mousing over things sometimes causes weird shifting as 
well.
Summary: Page content shifts without user interaction → Page content (animated GIF's) shifts without user interaction
It appears that it *is* animated GIF's and that after one full loop of the GIF, 
the GIF is then shifted to the left.

This looks fine on today's WinNT build, it will have to be tested on Win2000,

Seems fine to me on Windows 2000 Commercial build 2000091805. Also seems fine
on Linux Commercial build 2000091806. 

Jerry: can you verify this is fixed?

Note to anyone trying to reproduce: Watch the animated gif in the right frame 
till the shape changes three times.
What builds are you using? It's still doing it on my 2000110205 Win32 build.
Damn...wrong bug window...sorry
Reassigning to attinasi:
Marc, this should be fixed when you check in your fixes to prevent the
generation of reflows for animated gifs.

Probably will be, but that will just mask a reflow problem I think. If we are 
reflowing and it is shifting then couldn't we be having an incremental reflow 
problem here?

Chris, do you want to check this out before I close down the reflow?
