Why do the title bar on Firefox and taskbar on Windows 7 leave distorted image when a list of bookmark folders crosses either one ?

I use lots of folders in my bookmarks list. I have noticed that with both AMD and Nvidia based video cards, that if I am using a folder in my bookmarks list that has lots and lots of bookmarks, the list of bookmarks will cross both the title bar area of Firefox and the taskbar on Windows 7 at the bottom. When this happens, both the title bar on Firefox versions 8-10 and the taskbar at the bottom will leave images from the bookmark list that don't go away (unless I use F11 view fullscreen to clear away the image and restore to normal ). If I am using a Matrox video card, this doesn't happen. Why is this?

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Hey cor-el,

Wow. That did it. You are a genius! Thank you, thank you. It's very important that I be able to use the folders with saved bookmarks feature for my business which I rely on daily.

I unchecked the "use hardware acceleration feature" where you said it was in Firefox 9 browser and it resolved the problem immediately. I am using an Nvidia GS8400 video card. I was having the same problem on the new ATI/AMD video cards too (haven't tested though on ATI computer yet). My Matrox M9120 doesn't do that at all though. Do you have any idea why that is ? Is it a software conflict between Nvidia or AMD drivers and Firefox?

One more question on your response solution, why do you recommend upgrading to current video card drivers since un-checking the "hardware acceleration" feature in Firefox works? The video card drivers on the disc that came with the card I am using were supplied by the manufacturer and released last year. Shouldn't that be good enough?
