This is not specific to the web site listed.  When I open a window tab, the
browser "edges" will generally begin to flicker, seeming to flick the text and
images in the pane up and down by a few pixels, as if it cannot fix to one
position or another.  As well, this seems to occur if I open a website that has
an image larger than the browser's viewing pane.

Reproducible: Always

Steps to Reproduce:
1.a. Middle-click to open a tab from a link
1.b. Open an image larger than the pane of the viewing window

Actual Results:  
In both cases, the browser window will flicker back and forth.  This does not
affect other open Mozilla windows.  In the case of tabbed viewing, closing the
tabs does not alleviate the problem; it requires closing that window and opening
a new browser window.

Expected Results:  
Mozilla should reposition the viewing window in a fixed position, and then
reposition again when the tab is closed.  In the case of images, it should open
a scroll area to conceal the area of the image beyond the edge of the viewing
area, and find a fixed position.

I was using the original theme.  This is an initial install of Mozilla, though I
did have Netscape 7.1 installed prior to this installation.

* I've encountered the same problem with Mozilla 1.5 final, downloaded toady
   [ Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 ]
* the same happens with RC1 that i installed afterwards for testing
   [ Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20030916 ]
* I didn't have this problem with any final 
  release before [... using mozilla heavily since 1.1 :-) ...]

some more information: 

- clarification: 'flickering' means that the whole page content 
  (...everything  between the mozilla toolbars and statusbar...) gets shifted
  vertically by one pixel and then snaps back to its original position, quite 
  fast (about 3 or 4 times per second?)

- reproduction: pick any mozilla window, press ctrl-t to open a 
  second tab -> already now the 1-pixel bordering line just before the mozilla 
  status bar starts flickering

- by closing but the last tab and then using page reload, the 
  flickering most times disappears

- It does *NOT* happen on all machines!
   -> my new 2.66 GHz pentium 4 is affected
   -> both my old 866 Mhz and my Laptop (700 Mhz) are okay
  all of them running win2k and using the very same 1.5 build

- some graphics info on the system having the problem (in case 
  this helps anything)
   . hercules 3d prophet 8500 128mb, using DVI output
   . 1280x1024 resolution with 16bit high color palette

please tell me if there is more information i can provide or further 
tests i can do.

regards, martin

After a windows98 low memory crash causing the registry to revert to an earlier
copy, I reinstalled window patches and eventually reinstalled mozilla.

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.5) Gecko/20031007

Mozilla now flickers (read bounces) when I open a new tab (no page displayed).
The best indication is the bottom edge of the frame strobes. I close the tab,
the first (and only) page (this page) bounces: bottom edge strobes, text bounces
up and down (just enough pixels to reitate) and scrollbar bounces as if trying
to alternately finding top and bottom edges. I reload the page, usually the
flicker stops.

I am uncertain if the windows patches is causing this new behavior, but mozilla
performed properly before the crash and I am a heavy tab user.

I'm seeing this on ONE of my boxes.  Does it on any page, with or without tabs.
 Even does it on the default homepage for firefox.  What info can I provide to
help debug this?
