Created attachment 364380 [details] screenshot of display corruption. Description of problem: When viewing the website http://heraldry.sca.org/laurel/precedents/francois/wreath.html, firefox's graphics display goes wonky; the top of the screen starts wobbling, and as you page down the website, text starts building up until you cannot read anything because it is layer after layer of text. I've attached a number of screenshots. Note that the screenshots do not actually display what I see on the screen; the screenshots only display some of the corruption, I was unable to get a successful screenshot of the layered black text. I have a thinkpad X200-S with an Intel Mobile Intel GM45 Express Chipset. Version-Release number of selected component (if applicable): How reproducible: I've been able to reproduce it after (a) closing the tab and reopening it, (b) closing firefox and reopening it, and (c) restarting the computer and reopening it. Steps to Reproduce: 1. Open a new tab in firex 2. Put in URL 3. page down. Actual results: See above Expected results: The webpage should render appropriately. Additional info: The same problem does not occur when the same webpage in the same version of firefox/fedora is run on a Thinkpad T61 with an Intel 965GM graphics card.

Looks like a pango issue to me. Reassigning.
If it fails with one GPU and works with another, keeping the same software versions, that's clearly a GFX driver bug

I didn't attach the file X server config file (/etc/X11/xorg.conf) because I couldn't find it.
I just discovered that I have the same rendering problems when I view the page in Firefox 3.5.3 on Windows Vista SP2 (on the same thinkpad X200-S with an Intel Mobile Intel GM45 Express Chipset). The same problem also occurs on a different page in the same subdirectory: http://heraldry.sca.org/laurel/precedents/francois/pelican.html.
When I save them from Firefox, I can view them locally (on Vista) without the same rendering problems. (I haven't tried on linux yet).
OK, go to that site and use Help/Report Broken Web Site. Apparently, there is something wrong with the page itself, not with Firefox (or maybe there is something wrong with all versions of Firefox). Closing as NOTABUG
The problem is not the page: It is valid HTML 4.01. It contains no scripting. The CSS validates. The page displays properly on machines other than Sara's laptop. This bug should be reopened.

Not in our bugzilla (obviously it is not Red Hat-only bug), and I told you how to send a message to people who actually may help with it.

Aha, I didn't realize that "Report Broken Web Site" would sent a report to the Firefox devs; I thought it would just send a report to the webmaster, which would be useless. We'll do that.
