Description of problem: I have http://www.cnn.com as my home page. Sometimes, the image for the lead story shows corruption by being partly covered by other objects which Firefox draws. I've also seen the large flash ad at the top showing similar corruption. It's really hard to describe, so I've included a cropped screenshot of the first type. Version-Release number of selected component (if applicable): firefox-1.5.0.1-9 How reproducible: sometimes Steps to Reproduce: 1. Run FC5 Firefox using http://www.cnn.com as home page. Recheck it periodically. Actual results: Corruption as shown in screenshot. Expected results: No corruption. Additional info: Screenshot shows a piece of a Classmates.com flash ad, a piece of the Bugzilla web site (which I visited in a tab) and a piece of the search window in Firefox's upper right corner, overlaying the image under the lead story title. I have Flash, Java, Real Player, and MPlayer plugins installed.

Looking at it again, it's now showing a fragment of the display from Thunderbird which is also currently running. So it can be corrupted by pieces from other applications. So far I've only seen the corruption in Firefox, though.
I suspect this may be due to a hardware flaw in the motherboard's integrated video, and am closing.
