See bug 38, bug 4465 and Issue 13649. We could improve the application publishing experience by avoiding double title bars. Instead, Matchbox could propagate the application title to the client side by setting the "vncconfig" parameter "desktop".
Implemented in r26395 and r26397. Suggested test cases: Verify the client title: Firefox with multiple tabs, windows, popup windows. www.popuptest.com is good. Test the open and preferences dialog. Libreoffice Adobe Reader tlclient, Options -> Security -> Smart Card Details -> Add filter Time reporting on bug 4465.
Works as expected, titlbar is also update on the fly, for example using firefox and switching between tabs the title bar shows the corresponding information/title about the page loaded in the selected tab. Also verified using gedit which puts a * infront of document title if buffer is modified.
