           Summary: <canvas> stops working when out of view for some time
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://kouiskas.deviantart.com
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Canvas
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kouiskas at gmail.com

I've written a little <canvas> demo that renders metaballs: http://kouiskas.deviantart.com If you open that page then go do some browsing on other tabs for a while, when you come back to the demo the canvas is empty, despite the animation code still running (verified with developer tools). The duration it takes for the canvas to become empty seems random, sometimes it takes 5 seconds browsing on another tab, sometimes a minute. Even scrolling on the current window can trigger it sometimes (when the canvas goes out of view by scrolling), but most times won't.

If you inspect the page around the canvas you should find the javascript code that renders the animation.
