User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.3) Gecko/2008100314 GranParadiso/3.0.3 Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.3) Gecko/2008100314 GranParadiso/3.0.3 On my testing website when using: div.body pre{ position:relative; width:100%; overflow:auto; } in CSS on page which has <pre> blocks, part of page hiding under position:fixed header redraws badly when scrolling. This is especialy seeable, when you scroll very quickly. Same happens with default position (position:static) of the pre block. Reproducible: Always Steps to Reproduce: 1.Open the URL above in Firefox on Linux. 2.Scroll down the page using wheel or better by grabing the scrollbar and moving down the page quickly. 3.Watch the body part of the page moving under the position:fixed header for any redrawing problems Actual Results: Part of the header redraws badly when scrolling body part of page "under it." You can sometimes see the body part of page instead of header part. Expected Results: Body part of the page scroll smothly "under" the header part, while you can see the whole header all the time when scrolling, as can now see e.g. in Konqueror. For now I met the bug on Linux 2.6.26.x and 2.6.27.x, Xorg 1.4.2, both 32 and 64 bit, both NVidia proprietary and ATI open-source drivers using Arch Linux. Doesn't happen with Konqueror (KHTML), doesn't happen with Firefox on Windows.

Are you reporting this for Firefox 3.0.3, Nicky? For I see the described problem on Windows, but that is trunk-only.

Problem on Windows XP/Vista (trunk-only) regressed between 20080906021517 and 20080906040037 and a bug like Bug 442291 looks like a possible culprit.

Confirmed on Debian Testing 64bit, Intel Graphic Card. Epiphany 2.22.3 Mozilla/5.0 (X11; U; Linux x86_64; en; rv:1.9.0.3) Gecko/20080528 Epiphany/2.22 It looks like the bug is in Gecko or Xorg.
Downloaded Firefox 3.0.3 for Linux directly from Mozilla and CAN confirm the problem on Arch Linux Current 32-bit, ATI OSS drivers.
