There is a memory leek created in versions of Webkit greater than r38068. Flash content from one tab draws over the content from other tabs where different pages are loaded. The only way to clear the flash animation is to close the tab that contains it. For example load www.google.com and than on another tab www.novinite.com. Once that las page load and you go to the google tab you will see the flash animations from www.novinite.com
