Hi
Now I understand better. What I do not understand is why you have filed the
bug on vnc when it is the mate-panel that hogs the memory.
For this to be a vnc bug I think we need some proof that this is VNC
specific and this does not happen when starting a normal X session.
Vnc starts a desktop environment and mate-panel is a component of the Mate
desktop environment.
Or am I completely wrong?
