           Summary: Memory leaks in SVG filters
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows 7
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mkorourk at adobe.com

The attached HTML is a distilled example of far more complex HTML/JS which creates SVG content dynamically including filters.

With such content we are experiencing the memory footprint of Chrome infinitely increasing. Within 15 minutes the footprint grows from 24MB to 120MB and continues upward from there. The same problem does not happen in Firefox.

Note that in this simplified example, the filter is created but never attached to an SVG object. This was not the case in the original content and is part of the simplification of the original bug.

To reproduce, just open the HTML file and then watch the memory footprint of Chrome via Task Manager.
