Hi there is a screencast of this lag and is reproducible on multiple profiles and computers. 
This one may also be related to this but was resolved by updating the OS
Bug 477068 - Context menu and drop down list are slow to appear when running on Linux Terminal Server Project (remote X) (edit) 


Setup: Ubuntu 10 64 bits

2. Happens on a single computer, note that all my other computers are 32 bits except for a Windows 7 64 bits
3. Pretty much any menu click or right click has a lag which is variable, but still important.
4. Try Developer tools: console, below is an example of a right click. You can see a lag between seconds 44 and 48, but I don't see any meaningful error message (the ones that are there are unrelated to me, meaning that I reproduce the issue without the messages).

Debugger does not seem to report anything special.

I have attached a screencast where I perform a right click, then go into the button menu.
You can find it on dropbox
