Viewing attached page with GtkLauncher. Pressing the button will append a "1" to the input text field, but the new characters wont show unless you do something more, like clicking outside the GtkLauncher window or hover the input field. This problem does not occur in the qt port (using QtTestBrowser), there the "1"'s appear as expected when you click the button. Building and running on 64bit Ubuntu 11.10.

Thanks for reducing this bug! It's reponsible for a lot of *really bad* redraw issues.
