Well, not attributed to just one application. I would have thought this was a display problem, eg a failing graphic card or driver issue, but you are quite certain this only happens with IE.
What is even stranger though is that this happens to your laptop, and to a desktop PC at work.
As that's the case you need to look at the similarities between the two applications and the web sites you visit. For example, any of the add-ons that IE has installed in both computers, or common web sites you visit in both locations.
Does IE do this when it is opened in it's "No Add-ons" option?

I have a problem with IE (occurred in IE8 and reoccurred after install of IE9) on WIndows 7. At some point I will notice a tab has become unresponsive and the open window starts to deteriorate to a very gridlike image, closing out of the tab may be all takes to resume often I have to close IE completely and sometimes even reboot. Screenshots of the issue are posted at https://picasaweb.google.com/jnotte/IEScreenshots?authuser=0&feat=directlink
Thinking it is probably a resource issue, I have checked and cleared the windows temp files, the IE temp files, monitor refresh rate, used a memory cleaner and checked event logs for anything to narrow it down. This only happens in IE (8&9) and have not seen it in Chrome or Mozilla (Yes, there are times I can only use IE so switching not an issue plus I am sure it is related to my settings). I am working on a laptop primarily so not many monitor options but did notice that the same thing happened at work powerhouse destop. I do browse a lot and need to retrieve from the cache a lot but think I have made all setttings ample enough to accomodate space required. I am going to try to post screenshots of the tabs when the image deteriorates. Any suggestions would be appreciated. Overall, I am a high level user so welcome technical/complex suggestions. Most likely, I have already eliminated more basic causes but anything is possible. Thanks.
