From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0.0) Gecko/20020530 BuildID: 2002053012 Mozilla is not crashing but is not repainting widgets correctly. Many widgets will not redraw unless they get a mouse-over event. Some (like container widgets) won't even re-draw with a mouse-over. Movement does not force a re-draw so the wrong bit patterns (typically something from a window underneath Mozilla) are moved when the browser moves. Sometimes (not always) an expose event does not force a repaint, sometimes it will. All widgets seem to suffer from this problem. I cannot determine what starts this happening. But Mozilla starts off behaving well. I have to unload Mozilla from memory and re-start it to get re-painting to happen. Reproducible: Always Steps to Reproduce: 1. Use mozilla on any site. 2. Open several tabs, maybe several windows 3. It will eventually happen. Actual Results: Exactly the problem described. Expected Results: Widgets should re-paint themselves from all events like expose, mouse-over, etc. Machine is an AMD 900 Thunderbird with a Matrox G450 running Win93SE.
An additional clue: By minimizing and restoring the windowing several times I was able to pin down that only two areas of the browser are re-painting upon exposure. The HTML rendering window (not tabs) and the sidebar rendering window (without its title bar) are repainting. The window elements (title bar, border, etc.) are repainting. But no other widgets will repaint (including menu, navigation, status panel, links bar, and sidebar controls.
I have the same problem. It ONLY happens in Mozilla, but it happens in the new 1.1 alpha, and was in 1.0-release. I don't remember how many previous editions it happened it, sorry. It's quite serious and frequent. Sometimes Mozilla has been running a day, or sometimes a couple of minutes, before this sets in, and generally it takes a reboot to fix it. Restarting Mozilla does not fix it. Mouse-over displays things again. But the actual rendered window is also spooged, and has to be scrolled up/down to display correctly. A non-scrolling (small) page thus can't be seen, because when you click to it, the old page remains in place. So do application windows that paint over the screen when they go in front of it. My configuration: Athlon 1000 (Thunderbird) with 128MB, EPoX mobo with VIA chipset. Matrox G400 video, 32 MB, Driver rev 6.72.016. Win98 First Edition. (I even upgraded IE to v6 with Windows Update hoping it might bring in some new base code, but that didn't help. I am using IE6 to enter this note. That does not make me happy.) Because this is not a common bug, and doesn't occur at work on my ThinkPad, and I notice that the original post here also included a Matrox card, I am becoming suspicious that it's an interaction with the Matrox drivers.
Some additional input: Using Mozilla 2002061104, I updated the Matrox graphics drivers to the latest Beta level, 6.83b. This did not help. Nor did unchecking "use device bitmaps caching". I notice that Mozilla was fine last night but was in spooged mode this morning, while the computer had just been sitting there overnight (screen saver and monitor power-down as usual), so there was no particular web page that caused it; there is apparently some other factor. But it restored to normal use after shutting down Mozilla -- it doesn't *always* need a reboot. When the problem does occur, the rendering window is impacted. It only shows new material if it's scrolled in or out; newly loaded pages aren't shown right away, because the old page remains in place, somehow cached. Scroll a little and you can see part of each page up at once.
blah, this bug isn't useful, i've seen it, othes have too, but ...

Hello? Is anyone in the Mozilla org even watching this bug? The bug remains present and frequent in the 1.1 released version, and as a point of information it also occurs in Netscape 7.0-released. I can't find any workaround short of rebooting, or of course using a non-Mozilla browser.
One more example. I installed Phoenix 0.1 today. Very nice. But within a few hours, the bug had developed, impacting all Gecko-based browsers. So the Phoenix widgets and the displayed window are both spooged, just like regular Mozilla's.
Reporter(Drew Mills), what is your graphic/video card? Fred Goldstein, there seems to be a problem with Matrox graphic/video card. I don't know the exact bug id for it, but bug 147845 could be a good starting point
My card information: Installed in a Athlon Thunderbird 900Mhz Win98SE Matrox Millenium G450 DualHead 32MB Software version: 4.0 Files listed for card: G400.drv *vdd,*vflatd, G400.vxd G400DD32.DLL
I have the same problem. But I am using an Nvidia GeForce 2 card. Running Mozilla 1.3a at the moment. Win 98. After some amount of time (seems kinda random) Mozilla quits drawing pages until they are scrolled or I move the window off the screen and back or mouse-over widgets, etc. This has been happening for several versions at least. I have to reboot to solve the problem, restarting Mozilla doesn't fix it. Sometimes the problem seems to go away for a minute, but it comes back until reboot.
Same problem as comment #2 happens to me on both my wife's Win98 system and on my parents'. Very very different hardware setup; about the only commonality is Windows 98 (second edition). (They both have ATI video cards, but one's a Radeon 8500 and the other is an ancient Rage Pro Turbo.) Usually happens after about half an hour of browsing, maybe sometimes a bit longer; very repeatable, but I have no idea what triggers it. This is on Mozilla nightlies (starting several months ago) and on Firebird release 0.6 and nightlies up to and including the latest 20030529.
