The testcase that is still broken
(http://bugzilla.mozilla.org/attachment.cgi?id=76654&action=view) needed the
block frame patch that was backed out. I'd prefer a new bug on that specific
issue rather than expanding this one. Also, if there are any real sites that
show this, that would be good to note.

The block frame bug would have been fixed, but most of the patch for bug 128133 
was backed out because of regressions elsewhere.  Only the table patch was left 
in.  I think the block patch should get in before 1.0 so that that we don't get 
ugly flickers in common dhtml code (since most dhtml is written in divs which 
are block tags).

A real life site that uses code affected by this bug is:

http://www.brainjar.com/

I was also planning on using the menu at brainjar for my own site, but I really 
can't if the flickering is still happening in 1.0.

Another site that might be affected is:

http://www.mozilla.org/newlayout/demo/xml/books.xml

when mozilla is resized, the text in one of the select boxes flickers.

I'll try to come up with more, but I think this is pretty pervasive for dhtml 
and really should be fixed by 1.0!

i see no flicer in the URL here, nor in the testcase, using 2002040903 XP.
i see severe flicker in bug 136555 though - perhaps another bug.

to be a bit more clear,

to reproduce the flicker at http://www.brainjar.com/dhtml/menubar/demo.html

1. Load the url
2. click on the "file" menu item.  Now move your mouse pointer to the right, 
mousing over the menu items as you go.  Now move the mouse pointer back over 
the menu items again back to file.
3.  While you do step 2, look in the top left corner of the window to see the 
flicker.
4. Reload the file and repeat to see it again.

Note:  The flicker only seems to happen while performing the steps above a 
single time. After that, no more flicker until a reload and repeat of the steps.

Marc,

Can this get fixed.  In bug 128133 you said this:

So, you have a patch that just needs a little extra attention to get it to work 
properly.  Can we do that before 1.0...or at least put it on the Trunk soon?

Cannot reproduce, following the given steps on Linux/GTKfe.

This is a layout bug, more a dbaron thing.

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

This smells like it's related to the auto-width-float stuff that's discussed in
bug 156522 comment 1, which may be a cleaner testcase except it requires using
an old tree or backing out the other patches related to that bug.

I'll take the bug and change it from P4-Future to P2-Future, since it's actually
an issue I find somewhat interesting.  But lately I've begun to question even
when I'm going to have a chance to pull in my P1-Future bugs...

Can somebody please take a look at bug 129844 and check if it is the same bug.

This WFM now, maybe the fix in bug 129844 solved this?

Comment 13

[Jacob Kjome]

I'd have to say that this is a WFM.  Tested with 20030426 Mozilla Firebird on
Win2k (sp3).  I see no flicker whatsoever in any of the testcases.
