Windowsformshost memory leak

My problem is we have a deployed application, where people type in textboxes, so this is causing the behavior of the PresentationHost. WinForms is in the WindowsFormsHost.

So we can't just switch the System. WebBrowser to the Xaml control although we might just do that because it doesn't help with the ReportViewer problem. This happens even if the WebBrowser doesn't even display a web page, as you can see from this example. Is there some known issue or workaround for this? Tuesday, October 27, PM.
