Bug Description
When brigning up a context menu, in firefox by a right click in a web page the context menu take 2-3 second to appear, the same thing happen when clicking a drop down list.
The same bug appear in liferea when rightclicking in the message display.
This is on a ltsp-cluster setup on Intrepid.
The easiest way to reproduce this bug is to have a X server accepting remote connections then start firefox from another computer using DISPLAY=<ip>:0
Firefox is usually fast (as if it was local) but when you right-click it takes 2-3 seconds before the drop-down menu appears. This has also been confirmed with liferea, so it's likely xul-related.
It makes the user experience a lot worse than it was with Hardy's firefox/xul where it was local-like performances for drop-down menus and contextual menus.
This has been tested on the exact same network and same computers on both Hardy and Intrepid, so the network performances, cpu usage or video drivers are not at fault (tried with intel, via and ati hardware).
