Figure I'll mention this here as well.

When viewing websites with background images, such as twitter.com or my own website at www.markheadrick.com and I change to another tab for 2 minutes (this amount of time is repeatable anyway) I get a flicker of a black background before the page is fully drawn. If I have multiple tabs with the same background image, only the first tab will show the flicker. It's like it's loosing the image in memory or something. It has done this with Firefox in Safe Mode and with a new, clean profile. It has also done this with Hardware Acceleration off.

Windows 7 Pro 64bit w/ NVidia 550ti and 314.22 drivers. Newer drivers are more problematic which is why I have stayed with these.

Again, only pages with background images seem to show this flicker. Did not happen with Firefox 35 on my system.

I created a bug for it here: https://bugzilla.mozilla.org/show_bug.cgi?id=1137082

Thanks, Mark H

Actually managed to capture what I see for a split second after going back to the tab. This is my website at http://www.markheadrick.com

Let's try this.

Remove History For One Site Open the History Manager <Control><Shift> H. In the search bar, enter the name of the site. Right click on one of the listings and select Forget About This Site. This should remove all information, including any passwords / settings.

No difference. It was doing it right after I cleared all cache, cookies, browser and download history, forms, website data, etc. It would do with websites that I had never been to previously (that had background images) when I would go back to their tab.

Well, I am out of ideas. I've called the big guys to help you. Good luck.

What are your default color settings?

    "Allow pages to choose their own colors, instead of my selections above"

I've had that set since day 1. It's never not been that. The page looks correct, the background image just flickers black for a split second when I click back on the tab after looking at something else for a couple minutes.

Looks like Firefox 37 Beta 2 corrects the problem or at least it doesn't happen in it.
