hidden fixed div causes visible absolute div to be displayed incorrectly when scrolling
User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020623 Debian/1.2.5-0.woody.1 Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.5a) Gecko/20030721, Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.4) Gecko/20030529, Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.3.1) Gecko/20030425 When the page is scrolled, the part of the main part (position:absolute) of the page that would be obscured by a popup window (position: fixed) if the popup was visible is scrolled differently than the rest of the main part, causing text and images not to align properly. Reproducible: Always Steps to Reproduce: 1.Load the URL. 2.Scroll. Actual Results: Scrolled areas should be displayed properly. Expected Results: Some regions of the screen do not display the scrolled areas correctly. The problem can be reproduced with all three versions of Mozilla mentioned above. With Mozilla 1.3.1, the problem can be avoided by setting the visibility of the popup window to 'hidden' with a script, for example using <body onload="...">, even though the visibility is already 'hidden' according to the style sheet (this method is used in the URL above). On Windows (Mozilla 1.4) and with Mozilla 1.2 on MacOS 9, the text does not align while scrolling, but as soon as scrolling stops, the text realigns. No such problems using Mozilla 1.0 on Debian/GNU Linux Woody.
->views, but perhaps a duplicate

This works for me. Which is surprising, since it is a duplicate. *** This bug has been marked as a duplicate of 203439 ***

I'm not sure whether this is a real duplicate of 203439. 203439 talks about slow scrolling, but on the Mac, we actually have real screen distortion. I just verified the bug on MacOS X with Mozilla 1.7 and Firefox 0.9. The problem still exists. Camino 0.8 does not exhibit this problem. Does it use a different rendering engine?

Do you still see this problem using Firefox 3.5? Please update the bug, and close/alter bug if appropriate.

No reply, INCO. Please reopen if you are seeing this in Firefox 3.5.2 or later in Firefox safe mode and a new profile with the latest plugins. http://support.mozilla.com/kb/Safe+Mode http://support.mozilla.com/kb/Profiles

Let's call it WORKSFORME then, this certainly isn't INCOMPLETE, since the bug contains a clear and concise testcase. Anyway, this might haven been fixed by bug 352093.
