User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.4b) Gecko/20030507 Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.4b) Gecko/20030507 The page given (www.oldversion.com) is simply na example page indicative of nothing specific in and of itself. Any page with multiple links or graphic images (i.e. yahoo/lycos groups) or complex rendering (i.e. most professionally done webpages) will not render correctly after either short or extended usage (veries) on WIndows98 with 8MB NVIDIA VANTA chipset. Effectively, after rendering between 1-30 web pages, the browser will refuse to refresh either when new windows or created, or when links in a given window are clicked. Resizing the window restores the actual (new) content, but remaximizing results in image corruption that clear when the scroll bar is utilized. Restarting of the browser fixes this problem. Also, browser responsiveness drops immeadeately prior to this bug manifesting itself (i.e. opening new windows suffer a speed decrase of approx 25%-50% for one or two instances before the bug manifests itself.) Updating VANTA drivers and/or Direct X version (8 - 9), has no effect on this bug. Likewise, clearing both browser and system memory cache has no effect on the bug. This bug first manifested itself in browser version 1.3, which leads me to suspect that it has something to do with the implementation/integration of the new "smooth scrolling" code. Reproducible: Always Steps to Reproduce: 1.Load complex web pages or web forums 2.Repeat, Repeat, Repeat 3.Lack of window refresh/webpage corruption will eventually appear. Actual Results: The lackf of windows refresh/web page corruption appeared, taking being 5-30 minutes to manifest itself Expected Results: The same as above. What the Mozilla team should do is check the current page rendering codebase vs. 1.0 release and then systematicly review every change/enhancement that might be interpreted as "chipset specific", and make such enhancements configurable via the about:config panel, thus allowing possibly inadvertantly conflicting optimizations to be turn off at the user level (with the coresponding lack of features/speed, of course). The theme being used currently is Grey Modern, but the bug seems to manifest itself equally well in both Modern and Classic. No actual crash of Mozilla occurrs when this bug takes place, so error codes are not generated. Incidently, in version 1.4b the "rollover madness" test in the XBL suite now crashes Mozilla, but if this has anything to do with thie particular bug, then I am not aware of it. My system configuration is as follows: P-III 550 128 MB RAM Vanta 8MB integrated graphics chipset Windows 98SE DirectX 8a (was 9, but was reinstalled when bug first appeared, on the assumption that is was a DirectX problem) Mozilla: 1.4b (bug also occurs in Mozilla 1.3 as well)

I have this bug also, and am able to reproduce it regularly. I have been looking at art websites of late (http://elfwood.lysator.liu.se/elfwood.html), and it happens very often (as described in bug #208123). After the refresh problem occurs, to clear up the problem, I simply close Mozilla, and open it again, and then the window refreshes fine (for a while). Also, when the refresh problem occurs, if I happen to have Internet Explorer open at the same time, the IE window is also unable to refresh. When I close and/or reopen Mozilla, the IE window is able to refresh again without having to close and reopen IE. (It does not matter if IE is open or closed for this bug to occur in Mozilla.) When the refresh problem occurs, my MS resource meter reads... System Resources: 48% free, User Resources: 68% free, and GDI: 48% free. Normally, the values are 70%, 70%, and 78% free. When I close Mozilla, it takes about a minute for the resource meter to go back to the normal values.

New Information on this bug. I believe, after extended testing, that this bug is do to a memory/system resource allocation error. In short, Mozilla, is not flushing its memory/system cache effectively for some reason, resulting in an eventual overflow and consequent browser window overwriting/corruption. Tracing this problem back though the builds, this problem first becomes evident at the Mozilla 1.2 branch, but for some reason escalated in severity in the 1.3/1.4 branch. By being unable to free up/reclaim system resouces, Mozilla will continue create these errors in all future builds. Please note that manually clearing the memory cache does not solve this problem - only a full shut down and restart of Mozilla does.
