           Summary: [Qt] Windowless Plugins : Poor Flash performance
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://www.channel4.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P4
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: plasm at roo.me.uk


Performance on http://www.channel4.com/ is poor with the new windowless plugin
implementation -- X & WebKit use 100% CPU when you move your mouse around the
Flash object, whereas this previously did not happen. Firefox & Opera do not
use 100% CPU on the same page.

Tested with QtWebKit r49937, Qt 4.5.2, Flash 10.0.32.18, X server 1.6.4
